[PATCH 15/28] drm/i915/tgl: Add additional ports for Tiger Lake

[Lucas De Marchi <lucas.demarchi@intel.com>]

From: Vandita Kulkarni <vandita.kulkarni@intel.com>

There are 2 new additional typeC ports in Tiger Lake and PORT-C is now a
combophy port. This results in 6 typeC ports and 3 combophy ports.
These 6 TC ports can be DP alternate mode, DP over thunderbolt, native
DP on legacy DP connector or native HDMI on legacy connector.
