We return -EINVAL everywhere else where we don't support a giving
config, e.g. lack of dpll, unsupported plane scaling, pixel format
mismatch of the primary plane (since we don't yet have per-gen lists
of supported formats for the primary plane) and so on. So I've figured
-EINVAL is good enough until we have something better with the test
mode for atomic modesets.
