[PATCH V2 4/6] drm/i915: Add the VCS2 switch in Intel_ring_setup_status_page for Gen7 to remove the switch check warning

[Zhao Yakui <yakui.zhao@intel.com>]

V1->V2: Follow Daniel's comment to update the comment

The Gen7 doesn't have the second BSD ring. But it will complain the switch check
warning message during compilation. So just add it to remove the
switch check warning.
