This doesn't work on my PowerBook. AFAIR the CP writeback isn't reliable

This doesn't work on my PowerBook. AFAIR the CP writeback isn't reliable
with at least older Apple AGP bridges and probably others as well, whi
This enables writeback for the CP read pointer and
scratch regs on the remaining radeon asics.
