Subject: [PATCH] drm/amd/display: enable more strict compile checks

Currently, there are quite a number of issues that are quite easy for
the CI to catch, that slip through the cracks. Among them, there unused
variable and indentation issues. Also, we should consider all warnings
to be compile errors, since the community will eventually end up
complaining about them. So, enable -Werror, -Wunused and
-Wmisleading-indentation for all kernel builds.
