drm/i915/tc: Move TC port fields to a new intel_tc_port struct 

Move the TC port specific fields from intel_digital_port to a new
intel_tc_port struct. Pass an intel_tc_port pointer to all static
functions in intel_tc.c keeping dig_port accessible for these via a
pointer stored in the new struct.

The next patch will allocate the intel_tc_port dynamically, allowing
moving the struct definition to intel_tc.c.
