NXP's i.MX8 SoCs have system controller (M4 core) which takes control of clock management, power management, partition management, PAD management etc., other clusters like Cortex-A35 can send out command via MU (Message Unit) to system controller for clock/power management etc.. This patch adds basic IPC(inter-processor communication) support. Signed-off-by: Anson Huang <Anson.Huang@nxp.com>
