Subject: drm/i915/icl: unconditionally init DDI for every port
Git-commit: 00c92d929ac36848fbe88567ef14af947ab636e4
Patch-mainline: v4.19-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

On ICP, port present straps (from SFUSE_STRAP PCH register) are no
longer supported. Software should determine the presence through BIOS
VBT, hotplug or other mechanisms.

v2: Improve commit message (Lucas).
