So it doesn't find the network, which results in failure to mount root fs via NFS. Add an overlay dtso file that sets the dr_mode to host, allowing the USB controllers to work in host mode. With commit 15d16d6dadf6 ("kbuild: Add generic rule to apply fdtoverlay"), overlay target can be used to simplify the build of DTB overlays. It uses fdtoverlay to merge base device tree with the overlay dtso. apq8016-sbc-usb-host.dtb file can be used by drm-ci, mesa-ci.
