From: Ville Syrjälä <ville.syrj...@linux.intel.com>
Switch a lot of the intel_bios_foo() stuff to just accept the
devdata (VBT child device info) directly, instead of taking
detours via vbt.ports[].
Also unify the function naming scheme.
TODO: is intel_bios_encoder_{dp,hdmi}_ too much? Or should we
shorten to just intel_bios_{dp,hdmi}_ ?
