Force db410c to host mode to fix network issue which results in failure
to mount root fs via NFS.
See https://gitlab.freedesktop.org/gfx-ci/linux/-/commit/cb72a629b8c15c80a54dda510743cefd1c4b65b8

Compile the base device tree with overlay support and use fdtoverlay
command to merge base device tree with an overlay which contains the
fix for USB controllers to work in host mode. [suggested by Maxime Ripard]

v2:
  - Use fdtoverlay command to merge overlay dtbo with the base dtb instead of modifying the kernel sources

v3:
  - drm-ci scripts to use device tree overlay from arch/arm64/boot/dts/qcom and compile base device tree with overlay support

You don't need to compile it by hand, make dtbs should do it for you

That is also supported by the build system already, see
k3-am642-tqma64xxl-mbax4xxl-sdcard-dtbs in
arch/arm64/boot/dts/ti/Makefile for example.
