/*
 * The VIM3 on-board  MCU can mux the PCIe/USB3.0 shared differential
 * lines using a FUSB340TMX USB 3.1 SuperSpeed Data Switch between
 * an USB3.0 Type A connector and a M.2 Key M slot.
 * The PHY driving these differential lines is shared between
 * the USB3.0 controller and the PCIe Controller, thus only
 * a single controller can use it.
 * If the MCU is configured to mux the PCIe/USB3.0 differential lines
 * to the M.2 Key M slot, uncomment the following block to disable
 * USB3.0 from the USB Complex and enable the PCIe controller.
 * The End User is not expected to uncomment the following except for
 * testing purposes, but instead rely on the firmware/bootloader to
 * update these nodes accordingly if PCIe mode is selected by the MCU.
