drm/i915: Rename 'reg' to 'clk_reg' to unconfuse it from the other 'reg'
On VLV/CHV the rc6 residency calculations read a second register to determine the actual units used for the residency value. The variable name 'reg' where that register value is stored shadows the function argument 'reg'. That can easily leave the reader utterly confused, so rename the internal variable to 'clk_reg'.
