From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Turns out the current code for generating the LFP
data pointers doensn't work with certain VBTs, so
switch to just hardcoding the fp_timing table size,
and make the validator a bit more strict just to be
extra safe.

Ville Syrjälä (2):
  drm/i915/bios: Validate fp_timing terminator presence
  drm/i915/bios: Use hardcoded fp_timing size for generating LFP data
    pointers
