drm/i915: Don't enable the DDI-IO power in the TypeC TBT-alt mode

Browse source

According to the spec we should not enable the DDI-IO power domain if
the TypeC port is in the TBT-alt mode, so do that only in the other
TypeC modes or for non-TypeC ports. See the internal BSpec Index/22243.

v2:
- Add the internal BSpec reference to the log message. (José)
