[PATCH 0/4] soc: imx: add scu firmware api support

[Dong Aisheng]

Unlike the former i.MX Architectures, the new generation i.MX8 SoCs
(e.g. MX8QXP and MX8QM) contain a system controller which runs on a
dedicated Cortex-M core to provide power, clock, Pad, and resource
management. Communication between the host processor running
an OS and the system controller happens through a SCU protocol.
This patchset adds the SCU APIs which is implemented based on MU
and will be used by different system components.

It mainly consists of below parts:
1) MU library calls
1) Implementation of the IPC functions based on MUs (client side).
2) SCU firmware services APIs implementation ased on RPC calls which
   are mostly generated by SCU firmware
