Shouldn't this be wrapped in #if ARCH_TEGRA?

I had suggested this with Thomas Petazzoni's consolidated irq_chip patch
as well:

It seems like it would be a bit cleaner/easier to maintain if we relied
on the linker to stitch together a clksrc_of_match table, based on what
clocksources are being built into the image.  With that approach, at
least, a public initialization header wouldn't have to be exposed, and
this central table wouldn't have to be maintained (as more clocksrcs are
added, I forsee [admittedly trivial] merge conflicts).

Thoughts?
