mb/intel/tglrvp: Add PMC.MUX.CONx devices to devicetree for tglrvp_up3
Two usb Type-C ports under the actual mux device. Each port has its own
ACPI device entry. These nodes are the ones that the USB Type-C
port/connector device will refer to in order to configure the mux.
TEST=Verified the scope of PMC.MUX CONx in the SSDT on Tigerlake RVP
board.
