Video4Linux2 defines 3 RGB formats with 10 bits per color components
plus two optional alpha bits such that a pixel is then stored in a 4
bytes word.
Add a format info for the 3 10-bits RGB formats to the
v4l2_format_info() table in v4l2-common.c.

When ioctl debugging is turned on, the v4l_printk_ioctl() is used
to log the ioctl that is called. It uses an array of ioctl information
to log the ioctl name and it correctly checks for out-of-bound indexing
of that array. However, the array may have holes since not all ioctl
numbers are used. In that case the name of the ioctl is NULL.
It is harmless (printk handles NULL pointers), but not intended. Instead
use the v4l2_is_known_ioctl() function to determine if the ioctl
information is available or not.

Count how many Low Drive, Error and Arbitration Lost transmit
status errors occurred, and expose that in debugfs.
Also log the first 8 transmits that result in Low Drive or Error
conditions. That really should not happen with well-behaved CEC devices
and good HDMI cables.
This is useful to detect and debug HDMI cable issues.

HEVC and VP9 are running on the same hardware and share the same
chroma and motion vectors offset constraint.
Create common helpers functions for these computation.
Source and destination buffer height may not be the same because
alignment constraint are different so use destination height to
compute chroma offset because we target this buffer as hardware
output.
To be able to use the helpers in both VP9 HEVC code remove dec_params
and use context->bit_depth instead.

Since vb2 queue can store more than VB2_MAX_FRAME buffers, the
postprocessor buffer storage must be capable to store more buffers too.
Change static dec_q array to allocated array to be capable to store
up to queue 'max_num_buffers'.
Keep allocating queue 'num_buffers' at queue setup time but also allows
to allocate postprocessors buffers on the fly.

In the future a side effect of introducing DELETE_BUFS ioctl is
the create of 'holes' (i.e. unused buffers) in bufs arrays.
To know which entries of the bufs arrays are used a bitmap will
be added in struct vb2_queue. That will also mean that the number
of buffers will be computed given the number of bit set in this bitmap.
To smoothly allow this evolution all drives must stop using
directly num_buffers field from struct vb2_queue.
