This is not used by linux and not supported as part of imx SCU api, it
was added by mistake.
The constant value "9" has since been reassigned in firmware to a
different service.

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 patch implements the SCU firmware IPC function and the common
message sending API sc_call_rpc.
