drm/i915/gvt: Fix Comet Lake

Browse Source 
[ Upstream commit b75ef35bb57791a5d675699ed4a40c870d1da12f ]

Prior to the commit below the GAMT_CHKN_BIT_REG address was setup for
devices matching (D_KBL | D_CFL), where intel_gvt_get_device_type()
returns D_CFL for either Coffee Lake or Comet Lake.  Include the missed
platform.`
