Subject[PATCH] bus: ti-sysc: mark PM functions as __maybe_unused
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.

Fixes: 0eecc636e5a2 ("bus: ti-sysc: Add minimal TI sysc interconnect target driver")
