On i.MX8QM/i.MX8QX with system controller inside, the wakeup source is managed in SCFW(system controller firmware), if the wakeup source is belonged to system controller partition, then before Linux suspend, the wakeup source should be set to SC_PM_WAKE_SRC_SCU, and if the wakeup source is belonged to Cortex-A partition, the wakeup source should be set to SC_PM_WAKE_SRC_IRQSTEER, so need to add wakeup source SIP runtime service to get Linux kernel's wakeup source and set the correct wakeup source for system controller.
