Subject: [PATCH V5 1/4] dt-bindings: fsl: scu: add rtc binding

NXP i.MX8QXP is an ARMv8 SoC with a Cortex-M4 core inside as
system controller, the system controller is in charge of system
power, clock and secure RTC etc. management, Linux kernel
has to communicate with system controller via MU (message unit)
IPC to do RTC operation, this patch adds binding doc for i.MX
system controller RTC driver.
