ba4452b0c0 media: amphion: Add H264 and HEVC profile and level control
For format H264 and HEVC, the firmware can report the parsed profile idc
and level idc to driver, these information may be useful.
Implement the H264 and HEVC profile and level control to report them.

be9fd51072 media: amphion: handle picture skipped event
For some invalid frames,
especially multiple consecutive invalid frames,
they all can't be decoded,
then the firmware can send picture skipped event
to notify driver that some frames are invalid,
driver can return them with error flag.
