sata/mvebu: use #ifdef around suspend/resume code 



The newly added suspend/resume implementation for ahci_mvebu causes
a link error when CONFIG_PM_SLEEP is disabled:

ERROR: "ahci_platform_suspend_host" [drivers/ata/ahci_mvebu.ko] undefined!
ERROR: "ahci_platform_resume_host" [drivers/ata/ahci_mvebu.ko] undefined!

This adds the same #ifdef here that exists in the ahci_platform driver
which defines the above functions.
