drm/i915: Nuke the VLV/CHV PFI programming power domain workaround

Browse Source 
The hack to grab the pipe A power domain around VLV/CHV cdclk
programming has surely outlived its usefulness. We should be
holding sufficient power domains during any modeset, so let's
just nuke this hack.

v2: Fix typo in commit message (Ander)
