From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
Define the contents of VBT block 10 (Mode Removal Table).
There seem to be two variants:
- 8 byte entries for desktop systems
- 10 byte entries for mobile systems, with the extra
panel_flags being a bitmask of LFPs
It seems starting from HSW only the mobile variant is
used anymore.
