Commit b488c766442f ("ath11k: report rssi of each chain to mac80211 for QCA6390/WCN6855")
and commit c3b39553fc77 ("ath11k: add signal report to mac80211 for QCA6390 and WCN6855")
call debugfs functions in mac ops. Those functions are no-ops if CONFIG_ATH11K_DEBUGFS is
not enabled, thus cause wrong status reported.
Move them to mac.c.
Besides, since WMI_REQUEST_RSSI_PER_CHAIN_STAT and WMI_REQUEST_VDEV_STAT stats could also
be requested via mac ops, process them directly in ath11k_update_stats_event().

mac80211 started to delete debugfs entries in certain cases, causing a
ath11k to crash when it tried to delete the entries later. Fix this by
relying on mac80211 to delete the entries when appropriate and adding
them from the vif_add_debugfs handler.

Currently, firmware stats, comprising pdev, vdev and beacon stats are
part of debugfs. In firmware pdev stats, firmware reports the final
Tx power used to transmit each packet. If driver wants to know the
final Tx power being used at firmware level, it can leverage from
firmware pdev stats.
Move firmware stats out of debugfs context in order to leverage
the final Tx power reported in it even when debugfs is disabled.

Currently, creation of debugfs entries for TWT is failing during
hardware restart because of the residual TWT files which were
created during add_interface(). Since, struct arvif{} is memset
to zero upon add_interface() invocation, when the hardware restart
is triggered, arvif is memset to 0 and TWT files are attempted to
create again which will fail because of the residual TWT files
already in place, this leads to hardware restart failure.
Also, it is not a good idea to return error from add_interface()
because of debugfs file creation failures. Moreover, debugfs
framework can very well handle the errors in it's create file &
remove file APIs and the errors returned by these APIs are not
checked in most usecases.
Fix the HW restart failure by ignoring the errors returned from
the debugfs APIs.

Target copies spectral report and CFR report through dbring to
host for further processing. This mechanism involves ring and
buffer management in the Host, FW, and uCode, where improper
tail pointer update issues are seen.
This dbring debug support help to debug such issues by tracking
head and tail pointer movement along with the timestamp at which
each buffer is received and replenished.
Provide a debugfs interface to enalbe/disable dbring debug
support and dump the dbring debug entries.
Also introduced a new hardware param to add dbring debugfs support
for few hardwares which are using dbings.
Usage:
echo <dbr_id> <val> > /sys/kernel/debug/ath11k/ipq8074_2/
mac0/enable_dbr_debug
dbr_id: 0 for spectral and 1 for CFR
val: 0 - disable, 1 - enable.

Add debugfs interface "fw_dbglog_config" to configure firmware log level.
Configuration is done via WMI command WMI_DBGLOG_CFG_CMDID.
Command to configure,
echo "<dbglog_param> <values>" >
/sys/kernel/debug/ath11k/<hw>/macX/fw_dbglog_config
where dbglog_param can be,
1) WMI_DEBUG_LOG_PARAM_LOG_LEVEL - configure log level for a given module
here, <values> = <0xaaaa00bb>, 'aaaa' - module id and 'bb' - loglevel
2) WMI_DEBUG_LOG_PARAM_VDEV_ENABLE - enable debug log for a given vdev
here, <values> = vdev_id
3) WMI_DEBUG_LOG_PARAM_VDEV_DISABLE - disable debug log for a given vdev
except ERROR logs
here, <values> = vdev_id
4) WMI_DEBUG_LOG_PARAM_VDEV_ENABLE_BITMAP - set vdev enable bitmap
here, <values> = vdev_enable_bitmap
5) WMI_DEBUG_LOG_PARAM_MOD_ENABLE_BITMAP - set a given log level to all the
modules specified in the module bitmap. Command to configure for this log param,
$ echo "5 <values> <module_id_index> <is_end>" >
/sys/kernel/debug/ath11k/<hw>/macX/fw_dbglog_config
here,
<values> = <0xaaaaaaaa000000bb>, 'aaaaaaaa' - module bitmap and
'bb' - loglevel
<module_id_index> = index of module bitmap. Max module id is 512.
So, module_id_index is 0-15.
<is_end> = to indicate if more configuration to follow.
6) WMI_DEBUG_LOG_PARAM_WOW_MOD_ENABLE_BITMAP - Wow mode specific logging enable.
Command to configure for this log param,
$ echo "6 <values> <module_id_index> <is_end>" >
/sys/kernel/debug/ath11k/<hw>/macX/fw_dbglog_config
here,
<values> = <0xaaaaaaaa000000bb>, 'aaaaaaaa' - module bitmap and
'bb' - loglevel
<module_id_index> = index of module bitmap. Max module id is 512.
So, module_id_index is 0-15.
<is_end> = to indicate if more configuration to follow.
Sample command usage,
To enable module WLAN_MODULE_WMI and log level ATH11K_FW_DBGLOG_VERBOSE,
echo "1 0x10001" > /sys/kernel/debug/ath11k/<hw>/macX/fw_dbglog_config
To enable module bit map from 32 to 63 and log level ATH11K_FW_DBGLOG_VERBOSE,
echo "5 0xffffffff00000001 1 1" > /sys/kernel/debug/ath11k/<hw>/macX/fw_dbglog_config

Command "iw wls1 station dump" does not show each chain's rssi currently.
If the rssi of each chain from mon status which parsed in function
ath11k_hal_rx_parse_mon_status_tlv() is invalid, then ath11k send
wmi cmd WMI_REQUEST_STATS_CMDID with flag WMI_REQUEST_RSSI_PER_CHAIN_STAT
to firmware, and parse the rssi of chain in wmi WMI_UPDATE_STATS_EVENTID,
then report them to mac80211.
WMI_REQUEST_STATS_CMDID is only sent when CONFIG_ATH11K_DEBUGFS is set,
it is only called by ath11k_mac_op_sta_statistics(). It does not effect
performance and power consumption. Because after STATION connected to
AP, it is only called every 6 seconds by NetworkManager in below stack.

drivers/net/wireless/ath/ath11k/dp_rx.c:1662: undefined reference to `ath11k_debugfs_htt_ext_stats_handler'
This was because I had missed to move the static inline version of the function
(which are used when CONFIG_ATH11K_DEBUGFS is disabled) to debufs_htt_stats.h.
Also move ath11k_debugfs_htt_stats_req() at the same time. And create a stub

Some of the function declarations are for functions in debugfs_htt_stats.c and
debugfs_sta.c, move them to corresponding header files. As debugfs_sta.h didn't
exist create it.
Also in debugfs_htt_stats.h move dunction declarations to the end of the file.
No functional changes. Compile tested only.

As these functions are now defined in debugfs.c change the prefix to use
ath11k_debugfs_ as well.

If CONFIG_ATH11K_DEBUGFS is disabled there are warnings debug.c:
drivers/net/wireless/ath/ath11k/debug.c:36:20: warning: 'htt_bp_lmac_ring' defined but not used [-Wunused-variable]
36 | static const char *htt_bp_lmac_ring[HTT_SW_LMAC_RING_IDX_MAX] = {
| ^~~~~~~~~~~~~~~~
drivers/net/wireless/ath/ath11k/debug.c:15:20: warning: 'htt_bp_umac_ring' defined but not used [-Wunused-variable]
15 | static const char *htt_bp_umac_ring[HTT_SW_UMAC_RING_IDX_MAX] = {
| ^~~~~~~~~~~~~~~~
Fix this by refactoring debugfs code to debugfs.c. This also reduces the number
of ifdefs in debug.c and makes it easier to maintain the code.
