drm/i915/display: convert vlv_wait_port_ready() to struct intel_display

struct intel_display will replace struct drm_i915_private as the main
device pointer for display code. Switch vlv_wait_port_ready() over to
it. The main motivation to do just one function is to stop passing i915
to intel_de_wait(), so its generic wrapper can be removed.
