drm/i915/icl+: Don't enable DDI IO power on a TypeC port in TBT mode
The DDI IO power well must not be enabled for a TypeC port in TBT mode,
ensure this during driver loading/system resume.
This gets rid of error messages like
[drm] *ERROR* power well DDI E TC2 IO state mismatch (refcount 1/enabled 0)
and avoids leaking the power ref when disabling the output.
