The changelog doesn't really answer "why" this change is needed.  IOW, I
don't understand from the changelog exactly what problem this patch is
trying to solve.

AFAICT, it's just shuffling around the dependencies, and changes the
omap*_idle_init() calls into inline nops instead of function call nops.
