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

[ Upstream commit c3fbcf60bc74b630967f291f47f0d9d0de6fcea7 ]

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.
