Some regdomains have more than 23 valid 5ghz channels,
so 18xx's MAX_CHANNELS_5GHZ was increased to 32.
Since now we have different max 5ghz channels values
for wl12xx and wl18xx, add a new wl->max_channels_5ghz
field, and use it for scan channels configuration.

The scan APIs of 12xx and 18xx are totally different.
Use some common functions as much as possible (e.g.
for setting scan channels), but split scan.c into
chip-specific scan.c files, each implementing its
own scan mechanism.
(in other words - move most of the current wlcore's
scan.c into wl12xx, and implement a similar mechanism
in 18xx, according to the new api)
New wlcore ops are introduced in order to call the
chip-specific scan functions.
The template indices used for each scan (regular/scheduled)
are also different between the chips, so set the correct
indices used for each scan type after identifying the chip.

The new fw (8.5.0.0.28) is not backward compatible
with older drivers.
Use a new fw name (along with bumping the min
fw version), and add some code to fail
any boot attempt during the fw api alignment
patches (as the driver is not functional in
these transitional patches).
This code will be removed after the api alignment
will be done.

wlcore_op_set_key() calls wl18xx_set_key(),
which in turn executes some of his function
calls without acquiring wl->mutex and making
sure the fw is awake.
Adding mutex_lock()/ps_elp_wakeup() calls is
not enough, as wl18xx_set_key() calls
wl1271_tx_flush() which can't be called while
the mutex is taken.
Add the required calls to wlcore_op_set_key,
but limit the queues_stop and flushing
to the only encryption types in which
a spare block might be needed (GEM and TKIP).

Use number_of_assembled_ant5 phy param to indicate if A band is enabled:
if number_of_assembled_ant5 != 0 then it is enabled otherwise it is
disabled.
This aligns with phy implementation that uses this param both to indicate
if band is active and the number of antennas.
This parameter replaces enable_11a module param that was removed.
User-Space applications can use wlconf and/or INI files to disable A band
using this parameter.

When a function requests to recover, it would normally abort and will
not send any additional commands to the HW. However, other threads may
not be aware of the failure and could try to communicate with the HW
after a recovery was queued, but before the recovery work began.
Fix this by introducing an intermediate state which is set when recovery
is queued, and modify all state checks accordingly.

Don't use the ht_mode module parameter for determining AP supported
