mb/amd/chausie/devicetree: enable GFX HDA, ACP and XHCI2 devices

GFX HDA is the audio controller that provides audio output via the
external display connection, ACP is the audio coporcessor for the on-
board audio codec and XHCI2 is the third XHCI controller that provides
one USB 2.0 port. All those devices are used, so enable them in the
board's devicetree.
