[PATCH 1/2] mfd: ab8500-gpadc: add CONFIG_PM_RUNTIME to runtime_suspend/runtime_resume

[Jingoo Han <jg1.han@samsung.com>]

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.
