Subject: [PATCH v4 2/7] drm: ci: Force db410c to host mode

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

Use apq8016-sbc-usb-host.dtb which allows the USB controllers
to work in host mode.

Acked-by: Helen Koike <helen.koike@...labora.com>

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

v4:
  - Use apq8016-sbc-usb-host.dtb which allows the USB controllers to work in host mode.
    This patch depends on https://lore.kernel.org/lkml/20230911161518.650726-1-vignesh.raman@collabora.com/
