drm/i915: disable RCBP and VDS unit clock gating on SNB and VLV

The RCBP workaround still applies on these chips, and we need VDS as well.

v2: remove MB boot fetch that snuck in (Daniel)
    add workaround tags to comments for easier internal tracking (Daniel)
v3: only apply RCPB and VDS on SNB and VLV, IVB doesn't need them (Eugeni)
