drm/i915/pvc: Update forcewake domain for CCS register ranges 



The bspec was just updated with a correction to the forcewake domain
required when accessing registers in the CCS engine ranges (0x1a000 -
0x1ffff and 0x26000 - 0x27fff) on PVC; these ranges require a wake on
the RENDER domain, not the GT domain.

Bspec: 67609
