Add functions to create ancillary links, so that they don't need to

Now we have three types of media link, printing the right name during
debug output is slightly more complicated. Add a helper function to
make it easier.

To describe in the kernel the connection between devices and their
supporting peripherals (for example, a camera sensor and the vcm
driving the focusing lens for it), add a new type of media link
to introduce the concept of these ancillary links.
Add some elements to the uAPI documentation to explain the new link
type, their purpose and some aspects of their current implementation.

The original implementation removes reverse links for any input link and
assumes the presense of sink/source.
It fails when the link is a not a data link.
media_entity_remove_links when there's an ancillary link can also fail.
We only need to remove reverse links for a data link.

Add support for MEDIA_BUS_FMT_JPEG_1X8 media bus code to the
CSIS driver.
The MEDIA_BUS_FMT_JPEG_1X8 code is mapped to the RAW8 CSI-2 Data Type,
while the CSI-2 specification suggests to use User Defined Data Type 1.
As reported in the comment, the CSIS interface captures arbitrary Data
Types by using a pixel sampling mode not supported by the IP core
connected to it on i.MX SoCs.
As some sensors, such as OV5640, support sending JPEG data on the RAW8
Data Type and capture operations work correcty with such configuration,
map MEDIA_BUS_FMT_JPEG_1X8 to Data Type 0x2a.

Allow drivers to change the transmit timeout value, i.e. after how
long should a transmit be considered 'lost', i.e. the corresponding
cec_transmit_done_ts was never called.
Some CEC devices have their own timeout, and so this timeout value must be
longer than that hardware timeout value. If it is shorter then the
framework would consider the transmit lost, even though it is effectively
still in progress at the hardware level.

Use call_(void_)op consistently in the CEC core framework. Ditto
for the cec pin ops. And check if !adap->devnode.unregistered before
calling each op. This avoids calls to ops when the device has been
unregistered and the underlying hardware may be gone.

These two helper functions return true if the received message
contains the result of a previous non-blocking transmit. Either
the tx_status result (cec_msg_recv_is_tx_result) of the transmit,
or the rx_status result (cec_msg_recv_is_rx_result) of the reply
to the original transmit.

The results of non-blocking transmits were not correctly communicated
to userspace.
Specifically:
1) if a non-blocking transmit was canceled, then rx_status wasn't set to 0
as it should.
2) if the non-blocking transmit succeeded, but the corresponding reply
never arrived (aborted or timed out), then tx_status wasn't set to 0
as it should, and rx_status was hardcoded to ABORTED instead of the
actual reason, such as TIMEOUT. In addition, adap->ops->received() was
never called, so drivers that want to do message processing themselves
would not be informed of the failed reply.

If a transmit-in-progress was canceled, then, once the transmit
is done, mark it as aborted and refrain from retrying the transmit.
To signal this situation the new transmit_in_progress_aborted field is
set to true.
The old implementation would just set adap->transmitting to NULL and
set adap->transmit_in_progress to false, but on the hardware level
the transmit was still ongoing. However, the framework would think
the transmit was aborted, and if a new transmit was issued, then
it could overwrite the HW buffer containing the old transmit with the
new transmit, leading to garbled data on the CEC bus.

Don't enable/disable the adapter if the first fh is opened or the
last fh is closed, instead do this when the adapter is configured
or unconfigured, and also when we enter Monitor All or Monitor Pin
mode for the first time or we exit the Monitor All/Pin mode for the
last time.
However, if needs_hpd is true, then do this when the physical
address is set or cleared: in that case the adapter typically is
powered by the HPD, so it really is disabled when the HPD is low.
This case (needs_hpd is true) was already handled in this way, so
this wasn't changed.
The problem with the old behavior was that if the HPD goes low when
no fh is open, and a transmit was in progress, then the adapter would
be disabled, typically stopping the transmit immediately which
leaves a partial message on the bus, which isn't nice and can confuse
some adapters.
It makes much more sense to disable it only when the adapter is
unconfigured and we're not monitoring the bus, since then you really
won't be using it anymore.
To keep track of this store a CEC activation count and call adap_enable
only when it goes from 0 to 1 or back to 0.
