iio: common: ssp_sensors: Protect PM-only functions to kill warning

Browse Source 
If CONFIG_PM_SLEEP=n:

    drivers/iio/common/ssp_sensors/ssp_dev.c:644: warning: ‘ssp_suspend’ defined but not used
    drivers/iio/common/ssp_sensors/ssp_dev.c:669: warning: ‘ssp_resume’ defined but not used

Protect the unused functions by #ifdef CONFIG_PM_SLEEP to fix this.
