If we want to keep the debugfs in a separate file then we'll have to
expose the guts of the FBC implementation in intel_fbc.h (or some other
header) just for that, or we add a whole bunch of otherwise useless
functions that pretend to provide some higher level of abstraction.

Not really a fan of either of those options.
