drm/i915/display/debug: Expose crtc current bpc via debugfs
This new debugfs will expose the currently using bpc by crtc.
It is very useful for verifying whether we enter the correct
output color depth from IGT.
This patch will also add the connector's max supported bpc to
"i915_display_info" debugfs.
Example:
cat /sys/kernel/debug/dri/0/crtc-0/i915_current_bpc
Current: 8
