media: verisilicon: Fix TRY_FMT on encoder OUTPUT
Commit
f100ce3bbd6a ("media: verisilicon: Fix crash when probing
encoder") removed vpu_fmt from hantro_try_fmt(), since it was
initialized from vpu_dst_fmt, which may not be initialized, when TRY_FMT
is called. It was replaced by fmt, which is found using the pixelformat.
For the encoder, this changed the fmt to contain the raw format instead
of the coded format. The format constraints as of fmt->frmsize are only
valid for the coded format and are 0 for the raw formats. Therefore, the
size of a encoder OUTPUT device is constrained to 0 and the
v4l2-compliance tests for G_FMT, TRY_FMT, and SET_FMT fail.
Bring back vpu_fmt to use the coded format on an encoder OUTPUT device,
but initialize it using the currently set pixelformat on dst_fmt, which
is the coded format on an encoder.

media: Explicitly include correct DT includes
The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

media: i2c: add I2C Address Translator (ATR) support
An ATR is a device that looks similar to an i2c-mux: it has an I2C
slave "upstream" port and N master "downstream" ports, and forwards
transactions from upstream to the appropriate downstream port. But it
is different in that the forwarded transaction has a different slave
address. The address used on the upstream bus is called the "alias"
and is (potentially) different from the physical slave address of the
downstream chip.
Add a helper file (just like i2c-mux.c for a mux or switch) to allow
implementing ATR features in a device driver. The helper takes care of
adapter creation/destruction and translates addresses at each transaction.

media: ad5820: Drop unsupported ad5823 from i2c_ and of_device_id tables
The supported ad5820 and ad5821 VCMs both use a single 16 bit register
which is written by sending 2 bytes with the data directly after sending
the i2c-client address.
The ad5823 OTOH has a more typical i2c / smbus device setup with multiple
8 bit registers where the first byte send after the i2c-client address is
the register address and the actual data only starts from the second byte
after the i2c-client address.
The ad5823 i2c_ and of_device_id-s was added at the same time as
the ad5821 ids with as rationale:
"""
Some camera modules also refer that AD5823 is a replacement of AD5820:
https://download.kamami.com/p564094-OV8865_DS.pdf
"""
The AD5823 may be an electrical and functional replacement of the AD5820,
but from a software pov it is not compatible at all and it is going to
need its own driver, drop its id from the ad5820 driver.

media: ov5640: fix low resolution image abnormal issue
OV5640 will output abnormal image data when work at low resolution
(320x240, 176x144 and 160x120) after switching from high resolution,
such as 1080P, the time interval between high and low switching must
be less than 1000ms in order to OV5640 don't enter suspend state during
the time.
The reason is by 0x3824 value don't restore to initialize value when
do resolution switching. In high resolution setting array, 0x3824 is
set to 0x04, but low resolution setting array remove 0x3824 in commit
db15c1957a2d ("media: ov5640: Remove duplicated mode settings"). So
when do resolution switching from high to low, such as 1080P to 320x240,
and the time interval is less than auto suspend delay time which means
global initialize setting array will not be loaded, the output image
data are abnormal. Hence move 0x3824 from ov5640_init_setting[] table
to ov5640_setting_low_res[] table and also move 0x4407 0x460b, 0x460c
