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
