drm/i915/bios: Define VBT blocks 16,29,31 (Toggle List) contents

Browse Source 
Define the contenst is VBT blocks 16,19,31 (Toggle List).
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.
