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.
