[i915_bpo/SKL] Display corrupted after resume from suspend

Bug description:
A new video BIOS code from Intel causes a regression on Skylake where
the screen gets corrupted after resuming from suspend. This is a
blocker for OEM's, since new BIOS releases will include this VBIOS.
We've helped the vendor to verify a patch to fix it, and it's already
been queued for 4.3:
commit 39d9b85a4d4fa1642663ca0d208b5c246a3d6f50

drm/i915: set CDCLK if DPLL0 enabled during resuming from S3
Since BIOS RC 1.4 it would enable CDCLK PLL during BIOS S3 resume, then
driver needs to set CDCLK to avoid display corruption if DPLL0 enabled.
