freedreno/a6xx: WFI before RB_CCU_CNTL writes
This seems to be in a block of non buffered/context regs. Blob always
WFIs before write, so probably a good idea.
Annoyingly, compared to ealier gens, it is a bit harder to tell from the
register offset whether it is a buffered reg, it isn't as simple as
everything below 0x2000, it seems.
