Subject: [PATCH v3 2/2] media: verisilicon: Use V4L2_FMT_FLAG_ENUM_ALL_FORMATS flag
If V4L2_FMT_FLAG_ENUM_ALL_FORMATS flag has been set when calling
VIDIOC_ENUM_FMT ignore depth match and returns all the
hardware supported pixels formats. In this case all set
V4L2_FMT_FLAG_ALL_FORMATS when returning the pixels formats.

version 3:
- Set V4L2_FMT_FLAG_ALL_FORMATS flag when needed.
