Ugh... this one seems a bit over the top, to be honest. The only place
where this seems to be used is in arch/arm/mach-tegra/pm.c, but that
already uses one of the stubs from include/linux/clk/tegra.h, so I'm
wondering if we can't define that latter stub in a way to make it
unnecessary to declare this bogus pointer.

I'll play around with this a little bit.
