drm/i915/tgl: Drop support for pre-production steppings
Several post-TGL platforms have been brought up now, so we're well past
the point where we usually drop the workarounds that are only applicable
to internal/pre-production hardware.
Production TGL hardware always has display stepping C0 or later and GT
stepping B0 or later (this is true for both the original TGL and the U/Y
subplatform).
