Zhou Xiaoyong c749be9eb3 avcodec/mips: loongson optimize h264pred with mmi v3
1. no longer use the register names directly and optimized code format
2. to be compatible with O32, specify type of address variable with mips_reg and handle the address variable with PTR_ operator
3. ff_pred16x16_plane_ functions only support N64 ABI now
