Commit Message

The new bus driver causes a harmless compile-time warning when
CONFIG_PM is disabled:

drivers/bus/ti-sysc.c:440:12: error: 'sysc_runtime_resume' defined but not used [-Werror=unused-function]
 static int sysc_runtime_resume(struct device *dev)
            ^~~~~~~~~~~~~~~~~~~
drivers/bus/ti-sysc.c:421:12: error: 'sysc_runtime_suspend' defined but not used [-Werror=unused-function]
 static int sysc_runtime_suspend(struct device *dev)
            ^~~~~~~~~~~~~~~~~~~~

This marks the two unused functions as __maybe_unused to shut up
that warning.

Thanks applying into omap-for-v4.15/ti-sysc.
