mfd: ab8500-gpadc: Add CONFIG_PM_RUNTIME to runtime_suspend/runtime_resume

Add CONFIG_PM_RUNTIME to runtime_suspend/runtime_resume functions
to fix the build warnings when CONFIG_PM_RUNTIME is not selected.
This is because runtime PM callbacks defined by SET_RUNTIME_PM_OPS
are only used when the CONFIG_PM_RUNTIME is enabled.
