[Intel-gfx] [PATCH v3 1/3] drm/i915: Reuse the aux_domain cached

[José Roberto de Souza]

intel_dp_detect() caches the aux_domain in the beginning of the
function as it is used twice, so lets also use it as the aux_domain
don't change in runtime.

v3: returning intel_dp_retrain_link() error insted of
connector_status_disconnected
