drivers/intel/usb4: Add driver for USB4 retimer device
The USB4 retimer device needs to declare a _DSM with specific functions
that allow for GPIO control to turn off the power when an external
device is not connected. This driver allows the mainboard to provide
the GPIO that is connected to the power control.
