[Intel-gfx] [PATCH] drm/i915/tgl: Make Wa_14010229206 permanent

[Rodrigo Vivi]

From: Swathi Dhanavanthri <swathi.dhanavanthri at intel.com>

commit 63d0f3ea8ebb67160eca281320d255c72b0cb51a upstream.

This workaround now applies to all steppings, not just A0.
Wa_1409085225 is a temporary A0-only W/A however it is
identical to Wa_14010229206 and hence the combined workaround
is made permanent.
Bspec: 52890
