[why]
It's useful to know the max supported panel BPC and PIPE dither state
for IGT testing.

[how]
* Expose the connector max supported BPC for the panel via a debugfs file on the
  connector, "output_bpc".
  Example: cat /sys/kernel/debug/dri/0/DP-1/output_bpc

* Expose the dithering state for the crtc via a debugfs file "dither".
  Example: cat /sys/kernel/debug/dri/0/crtc-0/dither
