common/tigerlake: Add support for Alder Lake-P

Alder Lake-P is the same generation of graphics engine as Tiger Lake,
although there are definitely some differences, besides even just
little bits here and there. The most significant difference is the
power tree structure is completely different than TGL.

So far eDP panels have been tested.
