Jani Nikula cf6c422bf5 drm/i915/debugfs: add crtc i915_pipe debugfs file
The pipe may differ from crtc index if pipes are fused off. 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.

v2: User letters for pipe names (Ville)
