[Intel-gfx] [PATCH V3 4/6] drm/i915:Add the VCS2 switch in Intel_ring_setup_status_page for Gen7 to remove the switch check warning

[Zhao Yakui]

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.

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