soc/intel/broadwell: Separate PCH in devicetree

Flesh out the PCH configuration into a separate chip. Keep it within the
Broadwell SoC directory for now, to ease moving files around. The boards
were prepared beforehand and the devicetrees require next to no changes.

Tested on out-of-tree Acer Aspire E5-573, still boots.
