I think an interesting exercise would be to allow platforms to only
have local timers without any global timer.  I'm not currently sure
what that would involve, or even if it's possible, but I think for
MSM's sake it's something that needs looking into to remove some of
the complexity from their code.

It also means that if we do have local timers configured, we don't need
to support a global timer (unless we need it for sleep wakeup.)
