[Intel-gfx] [PATCH 1/3] drm/i915/bios: Move panel_type stuff out of parse_panel_options()

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

Parsing the panel_type is a bit special and should be done
before we parse anything else potentially panel-specific from
the VBT. So move it out from parse_panel_options(). It doesn't
neet to be there anyway since it'll do its own LVDS options
block lookup.
