Cover letter [PATCH -queue 0/2] loongson2f: add video acceleration support

This patchset add video acceleration support for loongson2f family machines via uncached accelerated TLB mapping.

We add a new option CPU_SUPPORT_VIDEO_ACC for loongson2f and it's successors, so all of them can share this souce code via selecting this option.

Thanks!
