For testing purposes, IGT needs to know the pipe. There's already a I915_GET_PIPE_FROM_CRTC_ID IOCTL for this. However, the upcoming Xe driver won't have that IOCTL, and going forward, we'll want a unified interface for testing i915 and Xe, as they share the display code. Thus add the debugfs for i915 display.
