IPC MU has no power domain assigned and there could be IPC during noirq suspend phase, so IRQF_NO_SUSPEND flag is needed for IPC MU. However, for other MUs, they have power domain assigned and their power will be turned off during noirq suspend phase, but with IRQF_NO_SUSPEND set, their interrupts are NOT disabled even after their power turned off, it will cause system crash when mailbox driver trys to handle pending interrupts but the MU power is already turned off. So, IRQF_NO_SUSPEND flag should ONLY be added to IPC MU which has power domain managed by SCU, then all other MUs' pending interrupts after noirq suspend phase will be handled after system resume.
