drm/i915/gen11: Wa_1408615072/Wa_1407596294 should be on GT list

Browse Source 
commit d5a1224aa6 upstream.

The UNSLICE_UNIT_LEVEL_CLKGATE register programmed by this workaround
has 'BUS' style reset, indicating that it does not lose its value on
engine resets.  Furthermore, this register is part of the GT forcewake
domain rather than the RENDER domain, so it should not be impacted by
RCS engine resets.  As such, we should implement this on the GT
workaround list rather than an engine list.
