[Intel-gfx] [PATCH 4/6] drm/i915/icl: Use appropriate helper for a masked workaround

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

Instead of "open coding" WaEnableFloatBlendOptimization:icl via
wa_write_clr_set, which should be for non-masked workarounds, add a new
helper wa_masked_en_no_verify and use it.
