drm/i915: Drop the forcewake count inc/dec around register read on VLV

Browse Source 
VLV is the only platform where we increment/decrement the forcewake
count around register access. Drop the inc/dec on VLV to make the
forcewake code a bit more unified.

The inc/dec are not necessary since we hold the uncore lock around
the whole operation.
