v3 cover media: amphion: decoder add support to RealVideo

RealVideo, or also spelled as Real Video, is a suite of proprietary video compression formats developed by RealNetworks - the specific format changes with the version.
RealVideo codecs are identified by four-character codes. RV30 and RV40 are RealNetworks' proprietary H.264-based codecs.

amphion decoder can support decoding RV30 and RV40 streams.

v3
- define respective formats for RV30 and RV40

v2
- correct the format name from RealMedia to RealVideo

Hi Nicolas,
I'll fix the typo and improve style in v4 patch,
And for RV40, maybe a new fourcc like RV40E can be defined for encoding RealVideo 10. But this patch won't use this format, some encoder driver can add it in the future if it can support encoding the RealVideo 10
