[RFC PATCH v5 4/9] media: chips-media: wave6: Add v4l2 m2m driver support

Add v4l2 m2m stateful driver support for the
Chips&Media Wave6 video codec IP, including both encoder and decoder.

The following features and formats are supported:
Encoder (8bit only):
- Supported codecs: AVC, HEVC
- Supported input formats:
* V4L2_PIX_FMT_YUV420/NV12/NV21
* V4L2_PIX_FMT_YUV422P/NV16/NV61
* V4L2_PIX_FMT_YUYV
* V4L2_PIX_FMT_YUV24/NV24/NV42
* V4L2_PIX_FMT_RGB24
* V4L2_PIX_FMT_P010
* V4L2_PIX_FMT_ARGB32
* V4L2_PIX_FMT_RGBA32
* V4L2_PIX_FMT_XRGB32
* V4L2_PIX_FMT_ARGB2101010
- Supports multiplanar format
- Although 10-bit input formats are supported (e.g., P010, ARGB2101010),
encoded output is limited to 8-bit streams
- Supports crop
- Supports extensive v4l2 encoder control

Decoder (8bit only):
- Supported codecs: AVC, HEVC (8bit only)
- Supported output formats: V4L2_PIX_FMT_YUV420/NV12/NV21
- Supports multiplanar format
- Supports scale down
- Supports dynamic resolution change

Note: While other versions of the Wave6 IP may support VP9 decoding and
AV1 decoding and encoding those formats are not implemented or validated
in this driver at this time.
