mainboard/amd: Copy bettong to gardenia and update for build

Use bettong as the reference for the gardenia mainboard.
Update makefiles etc so it builds.

This patch intentionlly keeps the carrizo_fch.asl file to
remain synchronized with the AMD PI package.

Remove items that do not apply to the Stoney APU, rewrite the
comments associated with the PCIe devices, and fix up the
SPD register association to match the 00670F00 chip.h.
