ARM: at91: pm: add support for sama5d2 secure suspend
When running with OP-TEE, the suspend control is handled securely. Suspend can be entered using PSCI support. Since the sama5d2 supports multiple suspend modes, add a new CONFIG_ATMEL_SECURE_PM which will send a SMC call to select the suspend mode at init time. "atmel.pm_modes" boot argument is still supported for compatibility purposes but the standby value is actually ignored since PSCI suspend is used and it only support one mode (suspend).
