David Francis f284975ef2 drm/amd/display: Add backlight pwm debugfs
[Why]
ABM enablement testing can be automated if a way of reading
target and current hardware backlight is available

[How]
Expand debugfs interface with two new entries.
Hook directly into dc interface.  Units are as
a fraction of 0x1000 = 100%

Use the built-in amdgpu function for creating
read-only debugfs files
