[PATCH v4 11/11] media: rkvdec: h264: Support High 10 and 4:2:2 profiles

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, fixes decoding of:

- Hi422FR13_SONY_A
- Hi422FR14_SONY_A
- Hi422FR15_SONY_A
- Hi422FR6_SONY_A
- Hi422FR7_SONY_A
- Hi422FR8_SONY_A
- Hi422FR9_SONY_A
- Hi422FREXT18_SONY_A

The get_image_fmt() ops is implemented to select an image format
required for the provided SPS control.

v4:
- Change to use get_image_fmt() ops

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
