Hi,
There are 2 types of (PCIe + USB) expansion cards that are provided with
the AM654 board configurations.
1) 2 lane PCIe + USB 2.0 card is supplied with the AM65 IDK
configuration [1]
2) 1 lane PCIe + USB 3.0 card is supplied with the AM65 GP EVM
configuration [2]
Add DT overlay files for both cards.

Add the overlay dtbo file to a Makefile target so it can be
picked by the dtbs_install command.

From: Roger Quadros <rogerq@ti.com>
Enable both Serdes and PCIe dt nodes in order to get PCIe working in
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

From: Kishon Vijay Abraham I <kishon@ti.com>
Add overlay for PCIe (uses the second instance of PCIe in AM654x) and
USB3.0 SERDES personality card
The PCI3/USB3 card is provided with the AM65x GP EVM configurtion [1]
so apply the overlay to k3-am654-gp-evm.dtb
