Deepak S 96676fe3a1 drm/i915/chv: Set min freq to RPn on CHV.
With latest Punit FW, vgg input voltag drop falling to minimum is fixed.
So reverting the WA patch & moving to turbo freq opreation range to [RPn -> RP0]

This is not a 1:1 revert of the commit 5b7c91b78b.
You can refer to commit 5b5929cbe3 ("drm/i915/chv: remove
pre-production hardware workarounds") as the reason for the discrepancy
