r600g: implement compression for MSAA colorbuffers for evergreen
This adds the FMASK and CMASK buffers. They share the same resource with color data. COMPRESSION and FAST_CLEAR are always enabled if both FMASK and CMASK are allocated. We initialize the CMASK to a "compressed" state (not "fast cleared"), so that we can keep FAST_CLEAR enabled all the time. Both FMASK and CMASK must be present at the moment. If either one is missing, the other one is not used. v2: add cayman regs in the list Reviewed-by: Jerome Glisse <[email protected]>
