[Intel-gfx] [PATCH v3 06/18] drm/i915/bios: Split parse_driver_features() into two parts

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

We use the "driver features" block for two different kinds
of data: global data, and per panel data. Split the function
into two parts along that line so that we can start doing the
parsing in two different locations.
