If the type is VFL_TYPE_GRABBER, then also check device_caps
to see if the video device supports video and/or metadata and
disable unneeded ioctls.
Without this change, format ioctls for both video and metadata devices
could be called on both device nodes. This is true for other ioctls as
well, even if the device supports only video or metadata.
Metadata devices act similar to VBI devices w.r.t. which ioctls should
be enabled. This makes sense since VBI *is* metadata.

With recent changes, support for decoding multi-slice frames can be
easily added now.
Signal VPU if current slice is first in frame or not and add information
about first macroblock coordinates.
When frame contains multiple slices and driver works in slice mode, it's
more efficient to hold capture buffer in queue until all slices of a
same frame are decoded.
Add support for that to Cedrus driver by exposing and implementing
V4L2_BUF_CAP_SUPPORTS_M2M_HOLD_CAPTURE_BUF capability.

I2C ops are expensive, as the I2C bus typical speed is 100kbps.
Also, stats reading take some time, as it requires to retrieve a
certain number of packets to complete.
While we don't know the minimal for CXD2841er, trying to do it
too quickly is still a very bad idea.
So, add some sanity logic there, preventing to retrieve stats
faster than one second.
This shouldn't cause any issues with well behavior apps, as they

Up to now VPE was relying on the colorspace value of struct v4l2_format
as an indication to perform color space conversion from YUV to RGB or
not.
Instead we should used the source/destination fourcc codes as a more
reliable indication to perform color space conversion or not.
To do so, we rework the csc module to use "struct v4l2_format *" as
parameters, and reorganize the coefficients tables in a more logical
way.

It is often useful to figure out if a pixel_format is either YUV or RGB
especially for driver who can perform the pixel encoding conversion.
Instead of having each driver implement its own "is_this_yuv/rgb"
function based on a restricted set of pixel value, it is better to do
this in centralized manner.
We therefore add a pixel_enc member to the v4l2_format_info structure to
quickly identify the related pixel encoding.
And add helper functions to check pixel encoding.

commit 3dc2046ca7 ("[media] media: ti-vpe: vpe: allow use of user
specified stride") and commit da4414eaed ("[media] media: ti-vpe: vpdma:
add support for user specified stride") resulted in the Motion Vector
stride to be the same as the image stride.
This caused memory corruption in the output image as mentioned in
commit 00db969964 ("[media] media: ti-vpe: vpe: Fix line stride
for output motion vector").
