mb/intel/tigerlake: Add support for USB Type-C ports
Two usb type-c ports under the actual Mux device. Each port has its own ACPI device entry (node). These nodes are the ones that the USB Type-C port/connnector devices will refer to in order to configure the mux.
BUG=b:151646486 BRANCH=None TEST=Verify USB Type-C alternate mode (DP or TBT) along wth PMC control.
