[media] media: platform: pxa_camera: convert to vb2
Convert pxa_camera from videobuf to videobuf2.
As the soc_camera was already compatible with videobuf2, the port is
quite straightforward.
The special case of this code in which the vb2 to prepare is "too
big" in terms of size for the new capture format, the pxa_camera will
fail.

Remove the soc_camera adherence. Mostly the change removes the power
manipulation provided by soc_camera, and instead :
- powers on the sensor when the s_power control is activated
- powers on the sensor in initial probe
- enables and disables the MCLK provided to it in power on/off
This patch also drops support for inverters on synchronisation and clock
lines. It is assumed, if any board ever needs such inverters, support
for them can be added in the future

instead of declaring the uAPI structs using usual refs, e. g.:
.. _foo-struct:
Use the C domain way:
.. c:type:: foo_struct
This way, the kAPI documentation can use cross-references to
point to the uAPI symbols.
That solves about ~100 undefined warnings like:

This allows the adapter to continue operating in autonomous mode with

settings are also persisted in EEPROM.
A new module parameter is added to optionally also use the configuration

[media] cx231xx: can't proceed if I2C bus register fails
The driver should not ignore errors while registering the I2C
bus, as this device can't even minimally work without the buses,
as it uses those buses internally to talk with the several IP
blocks inside the chip.

[media] cx231xx-i2c: handle errors with cx231xx_get_i2c_adap()
The cx231xx_get_i2c_adap() function should return the I2C
adapter that will be used to talk with a device. It should never
be NULL, as otherwise the driver will try to dereference a
null pointer.
We might instead fix the callers, but if this condition
ever happens, it is really a driver bug, because i2c_port
should always be a value from enum CX231XX_I2C_MASTER_PORT.
Found when checking the code due to this bug:

This device uses GPIOs: 28 to switch between analog and

[media] mb86a20s: fix demod settings
With the current settings, only one channel locks properly.
That's likely because, when this driver was written, Brazil
were still using experimental transmissions.
Change it to reproduce the settings used by the newer drivers.
That makes it lock on other channels.
Tested with both PixelView SBTVD Hybrid (cx231xx-based) and
C3Tech Digital Duo HDTV/SDTV (em28xx-based) devices.

[media] mb86a20s: fix the locking logic
On this frontend, it takes a while to start output normal
TS data. That only happens on state S9. On S8, the TS output
is enabled, but it is not reliable enough.
However, the zigzag loop is too fast to let it sync.
As, on practical tests, the zigzag software loop doesn't
seem to be helping, but just slowing down the tuning, let's
switch to hardware algorithm, as the tuners used on such
devices are capable of work with frequency drifts without
any help from software.
