[PATCH 2/6] drm: ci: Force db410c to host mode

[Vignesh Raman]

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

Since this fix is not sent upstream, add it to build.sh script
before building the kernel and dts. Better approach would be
to use devicetree overlays.
