OMAP1: PM: register notifiers with generic clock ops even when !PM_RUNTIME

When runtime PM is disabled, device clocks need to be enabled on
device add and disabled on device remove.  This currently is not
happening because in the !PM_RUNTIME case, no notifiers are registered
for OMAP1 devices.

Fix this by ensuring notifiers are registered, even in the !PM_RUNTIME case.
