[libata] PM callbacks should be conditionally compiled on CONFIG_PM_SLEEP
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]
Because
SET_SYSTEM_SLEEP_PM_OPS(suspend_fn, resume_fn)
Only references the callbacks on CONFIG_PM_SLEEP (instead of CONFIG_PM).
