Yeah, non-static declarations need to be in header files, otherwise
there's not much point in them really (since the compiler can't compare
the delcaration with the definition).

we also need to split up our headers I think, and I plan to start doing
that when extracting bits and pieces from intel_display.c. In drm core at
least having 1:1 between headers and source files seems to work rather
well.

Meanwhile on Jani's patch:
