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 on 10-bit format buffers.
The new valid_fmt operation is implemented and return a valid pixelformat
for the provided SPS control.
Signed-off-by: Jonas Karlman <jo...@kwiboo.se>

Changes in v2:
- Only align decoded buffer instead of using frmsize step_width
