drm/radeon/kms: clean up multiple crtc handling for evergreen+ (v2)
evergreen+ asics have 2-6 crtcs. Don't access crtc registers
for crtc regs that don't exist as they have very high latency
and may cause problems on some asics. The previous code missed
a few cases and was not fine grained enough (missed the 4 crtc
case for example).
Fixes:
