[FFmpeg-devel] [PATCH] avcodec/mips: Fix MMI macro replaces in HEVC Decoder

The latest commit of Loongson MMI macro replaces were incorrect.
It makes a mass of green tints on HEVC videos when playing. I've
compared it with the older MMI implementation, and found out that
several lines have been replaced by wrong macros.
