When decoding a 10bits bitstreams HEVC driver should only expose
10bits pixel formats.
To fulfill this requirement it is needed to call hantro_reset_raw_fmt()
when bit depth change and to correctly set match_depth in pixel formats
enumeration.

version 4:
- Only set ctx->bit_depth when hantro_reset_raw_fmt() returns is ok.
