drm/i915: Apply Wa_1406680159:icl,ehl as an engine workaround
The register this workaround updates is a render engine register in the
MCR range, so we should initialize this in rcs_engine_wa_init() rather
than gt_wa_init().
Closes: https://gitlab.freedesktop.org/drm/intel/issues/1222
Fixes: 36204d80bacb ("drm/i915/icl: Wa_1406680159")
