Use new macro to create a sysfs control bitmap knob to control
print-to-trace in: /sys/module/drm/parameters/trace
todo: reconsider this api, ie a single macro expecting both debug &
trace terms (2 each), followed by a single description and the
bitmap-spec::
Good: declares bitmap once for both interfaces
Bad: arg-type/count handling (expecting 4 args) is ugly,
especially preceding the bitmap-init var-args.
