drm/i915/bios: Determine panel type via PNPID match
Apparently when the VBT panel_type==0xff we should trawl through
the PNPID table and check for a match against the EDID. If a
match is found the index gives us the panel_type.
Tried to match the Windows behaviour here with first looking
for an exact match, and if one isn't found we fall back to
looking for a match w/o the mfg year/week.
v2: Rebase due to vlv_dsi changes
v3: Adjust to .get_panel_type() vfunc
