[PATCH 5/5] crypto: suspend/resume callbacks should be conditionally compiled on CONFIG_PM_SLEEP

[Yuanhan Liu]

This will fix warnings like following when CONFIG_PM_SLEEP is not set:

        warning: 'xxx_suspend' defined but not used [-Wunused-function]
        warning: 'xxx_resume' defined but not used [-Wunused-function]
