Use fdtoverlay command to merge base device tree with an overlay
which contains the fix for USB controllers to work in host mode.

Another thing that I was discussing with David and Vignesh, since we
will need this overlay spinets not only for drm-ci but also for mesa ci
(and every body who uses the farms), would it be interesting to move it
to some place more official? like dts folders? Or would that be against
Linux policy?
