drm/panthor: add sysfs knob for enabling job profiling
This commit introduces a DRM device sysfs attribute that lets UM control
the job accounting status in the device. The knob variable had been brought
in as part of a previous commit, but now we're able to fix it manually.
As sysfs files are part of a driver's uAPI, describe its legitimate input
values and output format in a documentation file.
