>From display gen12 onwards to support dual EDP two instances of pps added.
Currently backlight controller and pps instance can be mapped together
for a specific panel. Extended support for gen12 for dual EDP usage.
v1: Iniital revision
v2: Called intel_bios_panel_init w/o PNPID before intel_pps_init. [Jani]
