The newly added suspend/resume implementation for ahci_mvebu causes a link error when CONFIG_PM_SUSPEND 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.
