Subject: [PATCH v3 2/9] arm64: dts: qcom: apq8016-sbc: Add overlay for usb host mode

Due to the presence of the fastboot micro cable in the CI farm,
it causes the hardware to remain in gadget mode instead of host mode.
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. This dtso file will be used
in drm-ci, mesa-ci.

Overlay DT file uses the sugar syntax [suggested by Dmitry Baryshkov and Maxime Ripard]
