drm/i915: Use encoder->devdata more

Browse Source 
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.

v2: Drop the redundant "encoder" from the dp/hdmi specific functions
