drm: ci: Use scripts/config to enable/disable configs

Instead of modifying files in git to enable/disable
configs, use scripts/config on the .config file which
will be used for building the kernel.

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/cb72a629

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

drm/ci: remove rebase-merge directory

Gitlab runner can cache git repository, including the unfinished rebase
merge status. New CI job will come as a fresh checkout, however this
will not destroy the unfinished rebase, failing our build script.
Destroy the unfinished rebase state.

drm/ci: fix DEBIAN_ARCH and get amdgpu probing

amdgpu driver wasn't loading because amdgpu firmware wasn't being
installed in the rootfs due to the wrong DEBIAN_ARCH variable.

rename ARCH to DEBIAN_ARCH also, so we don't have the confusing
DEBIAN_ARCH, KERNEL_ARCH and ARCH.

drm/ci: pick up -external-fixes from the merge target repo

In case of the merge requests it might be useful to push repo-specific
fixes which have not yet propagated to the -external-fixes branch in the
main UPSTREAM_REPO. For example, in case of drm/msm development, we are
staging fixes locally for testing, before pushing them to the drm/drm
repo. Thus, if the CI run was triggered by merge request, also pick up
the -external fixes basing on the the CI_MERGE target repo / and branch.

drm: Add initial ci/ subdirectory

Developers can easily execute several tests on different devices
by just pushing their branch to their fork in a repository hosted
on gitlab.freedesktop.org which has an infrastructure to run jobs
in several runners and farms with different devices.

There are also other automated tools that uprev dependencies,
monitor the infra, and so on that are already used by the Mesa
project, and we can reuse them too.

Also, store expectations about what the DRM drivers are supposed
to pass in the IGT test suite. By storing the test expectations
along with the code, we can make sure both stay in sync with each
other so we can know when a code change breaks those expectations.

Also, include a configuration file that points to the out-of-tree
CI scripts.

This will allow all contributors to drm to reuse the infrastructure
already in gitlab.freedesktop.org to test the driver on several
generations of the hardware.
