The System Controller Firmware (SCFW) controls RTC, thermal
and WDOG etc., these resources' interrupt function are managed
by SCU. When any IRQ pending, SCU will notify Linux via MU general
interrupt channel #3, and Linux kernel needs to call SCU APIs
to get IRQ status and notify each module to handle the interrupt.
Since there is no data transmission for SCU IRQ notification, so
doorbell mode is used for this MU channel, and SCU driver will
use notifier mechanism to broadcast to every module which registers
the SCU block notifier.

As resource power domain service is provided by SCU firmware, no
SS information required. So we can remove the SS indicator from
the domain names, then the domains defined can be better shared
among different SCU based platforms.

As the domain resource id in the same type may not be continuous, so it's
hard to describe all such power domains with current struct imx_sc_pd_range.
Adding the optional base for domain name index to address this issue.
Then we can add the discrete domains easily later.

Using bool instead 0/1 to indicate whether adding a postfix for domain
names which can improve the code readability and less confusing.

This is done via RPC call to SCU.

SCU power domain can be used in the same way by IMX8QXP and IMX8QM SoCs.
Make the driver support the fallback compatible string "fsl,scu-pd" to
allow other SoCs to reuse the common part.

Some i.MX SoCs contain a system controller that is responsible for
controlling the state of the IPs that are present. Communication
between the host processor running an OS and the system controller
happens through a SCU protocol. This patch adds SCU protocol based
power domains drivers.

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.
