drm/i915: Only wait for required lanes in vlv_wait_port_ready()

Browse source

Currently vlv_wait_port_ready() waits for all four lanes on the
appropriate channel. This no longer works on CHV when the unused
lanes may be power gated. So pass in a mask of lanes that the
caller is expecting to be ready.
