The 32 bit sched_clock interface now supports 64 bits. Upgrade
to the 64 bit function to allow us to remove the 32 bit
registration interface.

Patch is based on Linus' tip. Not event compile tested.

Build and run-tested, appears to work.

Should it go through xtensa tree, or through some other tree as a part
of a bigger conversion series?

If it can go through xtensa that sounds like the best option. Otherwise
we can send it through the tip/timers tree.

Ping? I don't see this patch in linux-next yet so should I send this
through the tip/timers tree?
