Subject: drm/i915: Init aux_ch for HDMI ports too
MIME-Version: 1.0

Git-commit: ac897d6bd7035390d621c283769b19a488ee15bc
Patch-mainline: v5.0-rc1
References: fate#326289
From ICL onwards DDI/TypeC ports - even in HDMI static mode - need to know
which AUX CH belongs to them, so initialize aux_ch for those ports too.
For consistency do this for all HDMI ports, not only for DDI/TypeC ones.
