[PATCH v2 1/3] drm/i915: set min delay to rpe delay (Efficient frequency).

[deepak.s@intel.com]

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

We use RPe here since it should match the Vmin we were shooting for.
That should give us better perf than if we used the min freq available.
System thermal can take the system to lowest possible freq (RPn). We are
making sure, we calmp the freq to min_delay (RPe).
