drm/radeon/kms: dynclks fixes
- only r4xx/r5xx/rs6xx/rs740 have clock gating atom table,
so disable it on r6xx. it's already disabled on r7xx
- check to make sure the clock_gating hook exists before
calling it. This avoids a segfault on asics without
that function.
- remove unused static power management function.
