Paulo Zanoni 3f704fa277 drm/i915: set CPT FDI RX polarity bits based on VBT
Check the VBT to see if the machine has inverted FDI RX polarity on
CPT. Based on this bit, set the appropriate bit on the TRANS_CHICKEN2
registers.

This should fix some machines that were showing black screens on all
outputs.
