I suppose we could, but that is only possible after this round of "moderization",
i.e. usage of CLOCKSOURCE_OF_DECLARE() et al.

Plus the move will require a bunch of mechanical crap such as read_aux_reg() which
only ARC defines (similar to headaches Noam had for his clksrc).

So if we could agree on the sanity of this round of changes, I can work towards
the imminent move into drivers.
