[PATCH v2 2/2] drm/i915/chv: Extend set idle rps wa to chv

From: Deepak S <deepak.s@linux.intel.com>

It is obsered on BSW that requesting a new frequency from Punit
does nothing when the GPU is in rc6, and if we let it enter rc6 with a
high frequency Vnn also remains high. Extending vlv_set_rps_idle()
workaround on CHV/BSW.
