[Intel-gfx] [PATCH 1/2] drm/i915/tgl: Fix REVID macros for TGL to fetch correct stepping

Fix TGL REVID macros to fetch correct display/gt stepping based
on SOC rev id from INTEL_REVID() macro. Previously, we were just
returning the first element of the revid array instead of using
the correct index based on SOC rev id.
