> Sounds good!

Drop "chip drivers/intel/pmc" since pmc is hidden and resource is inaccessible. Back to Caveh's "drivers/intel/tcss" through xhci's device ID "PCI_DEVICE_ID_INTEL_TGP_TCSS_XHCI -> 0x9A13". 
USB properties of usb2-port-number/usb3-port-number/sbu-orientation/hsl-orientation are assigned from devicetree's xhci(00.0d.00). With the generated SSDT PMC.MUX.CONx along with SSDT LPCB.EC0.CREC.USBC, the preliminary test shows USBC(GOOG0014) and PMC(INTC1026) are probed successfully.
