[Intel-gfx] [PATCH] drm/i915/icl: Remove Wa_1604302699

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin at intel.com>

It seems that the documentation does not reference this any more, plus,
bit 28 does not stick when written to the register.

Therefore I can only assume this is something which was documented in the
past but got removed from the hardware in the meantime.
