[PATCH 1/2] media: hevc: Remove RPS named flags

[Benjamin Gaignard]

Marking a picture as long-term reference is valid for DPB but not for RPS.
Change flag name to match with it description in HEVC spec chapiter
"8.3.2 Decoding process for reference picture set".
Remove the other unused RPS flags.
