arm64: dts: ti: Add DT overlay for PCIe + USB2.0 SERDES personality card

Browse source

Enable both SERDES and PCIe DT nodes in order to get PCIe working on
the SERDES PCIe x2 personality card.

The daughter card also has a USB 2.0 dual-role port. As the base board
already supports a 2.0 dual-role port, enable the port on the SERDES
card to be a host only port.

This will prevent user confusion as having 2 ports in device mode often
leads to confusion as to which port is bound to the gadget function driver.

The PCIe x2 card is provided with the AM65x IDK configuration [1]
so apply the overlay to k3-am654-idk.dtb
