This enables DSP IPC protocol between host AP (Linux)
and the firmware running on DSP.
DSP exists on some i.MX8 processors (e.g i.MX8QM, i.MX8QXP).
It acts like a doorbell. Client might use shared memory to
exchange information with DSP side.

The System Controller Firmware (SCFW) is a low-level system function
which runs on a dedicated Cortex-M core to provide power, clock, and
resource management. It exists on some i.MX8 processors. e.g. i.MX8QM
(QM, QP), and i.MX8QX (QXP, DX).
This driver manages the IPC interface between host CPU and the
SCU firmware running on M4.

help
The System Controller Management Interface firmware (SCMI FW) is
a low-level system function which runs on a dedicated Cortex-M
core that could provide misc functions such as board control.
This driver can also be built as a module.
