[Intel-gfx] [PATCH v2 3/4] drm/i915/chv: Set min freq to efficient frequency on chv

[deepak.s at linux.intel.com]

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

After feedback from the hardware team, now we set the GPU min/idel freq to RPe.
Punit is expecting us to operate GPU between Rpe & Rp0. If we drop the
frequency to RPn, punit is failing to change the input voltage to
minimum :(

v2: Change commit message
