[PATCH v2] drm/amd/display: enable more strict compile checks

[Hamza Mahfooz]

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 are
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.
