From: Ville Syrjälä <ville.syrj...@linux.intel.com>

Define the contenst is VBT blocks 19,30,32 (Display Configuration
Removal Table) contents. There are three variants of this block:
pre-IVB, IVB, HSW+, with each having slightly different entries.

Curiously many HSW/BDW machines seem to have both the IVB and HSW+
variants in their VBTs simultanously. No idea why.
