Add helper functions to calculate plane bytesperline and sizeimage,
these new helpers consider bpp div, block width and height when
calculating plane bytesperline and sizeimage.

Add NV15 and NV20 pixel formats used by the Rockchip Video Decoder for
10-bit buffers.
NV15 and NV20 is 10-bit 4:2:0/4:2:2 semi-planar YUV formats similar to
NV12 and NV16, using 10-bit components with no padding between each
component. Instead, a group of 4 luminance/chrominance samples are
stored over 5 bytes in little endian order:
YYYY = UVUV = 4 * 10 bits = 40 bits = 5 bytes
The '15' and '20' suffix refers to the optimum effective bits per pixel
which is achieved when the total number of luminance samples is a
multiple of 8 for NV15 and 4 for NV20.

Use bytesperline and buffer height to calculate the strides configured.
This does not really change anything other than ensuring the
bytesperline that is signaled to userspace matches what is configured
in HW.

Some SPS/PPS parameters are currently hardcoded in the driver even
though they exist in the stable uapi controls.
Use values from SPS/PPS controls instead of hardcoding them.

SPS parameters is validated in try_ctrl() ops so there is no need to
re-validate when streaming starts.
Remove the unnecessary call to validate sps at streaming start.

Add a rkvdec_valid_fmt() helper that check if a pixelformat is a valid

Use these new helpers in preparation for adding format validation ops in

Add a valid_fmt() ops to validate if a CAPTURE format is supported.
Expectation is that the valid_fmt() ops is a deterministic function and
the return value from get_fmt_opaque() ops is passed as input to the
valid_fmt() ops.
The CAPTURE format is reset when queue is not busy and format validation
fail.

Add support and enable decoding of H264 High 10 and 4:2:2 profiles.
Decoded CAPTURE buffer width is aligned to 64 pixels to accommodate HW
requirement of 10-bit format buffers.
The get_fmt_opaque and valid_fmt ops is implemented to select a CAPTURE
format suited for the provided SPS control.

v3:
- Add get_fmt_opaque ops, the expected pixelformat is used as opaque
- Add new valid_fmt ops that validate pixelformat matches opaque
- Update H264_PROFILE control max value
