[PATCH v4 04/19] drm/i915/bmg: Extend DG2 tc check to future

[Balasubramani Vivekanandan]

From: Radhakrishna Sripada <radhakrishna.sripada at intel.com>

Discrete cards use the Port numbers TC1-4 for the offsets. The regular
flow for type-c subsystem port initialization can be skipped. This check
is present in DG2. Extend this to future discrete products.
