Input: ad7879-i2c - wrap suspend and resume in CONFIG_PM_SLEEP
CONFIG_PM is defined when CONFIG_PM_SLEEP or CONFIG_PM_RUNTIME is defined,
however suspend and resume methods are only valid in the context of
CONFIG_PM_SLEEP. If only CONFIG_PM_RUNTIME is defined we get the following
warning (courtesy of Geerts randconfig builds):
ad7879-i2c.c: warning: 'ad7879_i2c_resume' defined but not used
