PM / Runtime: Fix loops in pm_runtime_clk_notify()
The loops over connection ID strings in pm_runtime_clk_notify()
should actually iterate over the strings and not over the elements
of the first of them, so make them behave as appropriate.
This fixes a regression introduced by commit 600b776eb39a13a28b090
(OMAP1 / PM: Use generic clock manipulation routines for runtime PM).
