[Intel-gfx] [PATCH v2 15/22] drm/i915/bios: Do panel specific VBT parsing later

[Ville Syrjala]

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

Move the panel specific VBT parsing to happen during the
output probing stage. Needs to be done because the VBT
parsing will need to look at the EDID to determine
the correct panel_type on some machines.
