[PATCH] PM / Runtime: Handle clocks correctly if CONFIG_PM_RUNTIME is unset

["Rafael J. Wysocki" <rjw@sisk.pl>]

From: Rafael J. Wysocki <rjw@sisk.pl>

Commit 85eb8c8d0b0900c073b0e6f89979ac9c439ade1a (PM / Runtime:
Generic clock manipulation rountines for runtime PM (v6)) converted
the shmobile platform to using generic code for runtime PM clock
management, but it changed the behavior for CONFIG_PM_RUNTIME unset
incorrectly.

Specifically, for CONFIG_PM_RUNTIME unset pm_runtime_clk_notify()
should enable clocks for action equal to BUS_NOTIFY_BIND_DRIVER and
it should disable them for action equal to BUS_NOTIFY_UNBOUND_DRIVER
(instead of BUS_NOTIFY_ADD_DEVICE and BUS_NOTIFY_DEL_DEVICE,
respectively).  Make this function behave as appropriate.
