[ARM] omap: move propagate_rate() calls into generic omap clock code

Browse Source 
propagate_rate() is recursive, so it makes sense to minimise the
amount of stack which is used for each recursion.  So, rather than
recursing back into it from the ->recalc functions if RATE_PROPAGATES
is set, do that test at the higher level.
