[Intel-gfx] [PATCH 16/28] drm/i915/tgl: update ddi/tc clock_off bits

From: Mahesh Kumar <mahesh1.kumar at intel.com>

In GEN 12 PORT_C DDI clk_off bit is not equally distanced to A/B,
it's at offset 24. Similarly TC port (5/6) clk off bits are at
offset 22/23. Extend the macros to cover the additional ports.
