media: videodev2: Add flag to unconditionally enumerate pixel formats
When the index is ORed with V4L2_FMTDESC_FLAG_ENUM_ALL the
driver clears the flag and enumerate all the possible formats,
ignoring any limitations from the current configuration.
Drivers which do not support this flag yet always return an EINVAL.
