[PATCH 1/2] drm: rcar-du: Iterate over connectors in rcar_du_crtc_atomic_check()

[Laurent Pinchart]

Replace iteration over encoders with iteration over connectors. This is
a bit more aligned with the atomic framework, but more importantly, the
change prepares for code that will need to access the connector.
