ahci_imx: Put #ifdef CONFIG_PM_SLEEP around suspend / resume functions

This fixes the following warnings when CONFIG_PM_SLEEP is not set:

drivers/ata/ahci_imx.c:284:12: warning: ‘imx_ahci_suspend’ defined but not used [-Wunused-function]
drivers/ata/ahci_imx.c:299:12: warning: ‘imx_ahci_resume’ defined but not used [-Wunused-function]
