drm/radeon/kms: pageflipping cleanup for avivo+
Avoid touching the flip setup regs while
acceleration is running. Set them at modeset
rather than during pageflip. Touching these
regs while acceleration is active caused hangs
on pre-avivo chips. These chips do not seem
to be affected, but better safe than sorry,
plus it avoids repeatedly reprogramming the
regs every flip.
