drm/radeon/kms: clean up multiple crtc handling for evergreen+ (v2)
commit b7eff394670366a42935bfbaef67a6f7185627d7 upstream.
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:

v2: fix typo noticed by Chris Bandy <cbandy@jbandy.com>
