From: Ville Syrjälä <ville.syrj...@linux.intel.com>
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.
