add dummy functions to avoid build failure when header files
are included, but drivers are not built.

The i.MX SCU soc driver depends on SCU firmware driver, so it has to
use platform driver model for proper defer probe operation, since
it has no device binding in DT file, a simple platform device is
created together inside the platform driver. To make it more clean,
we can just move the entire SCU soc driver into imx firmware folder
and initialized by i.MX SCU firmware driver.

Add resource management API, when we have multiple
partition running together, resources not owned to current
partition should not be used.

i.MX8 SoCs DTS file needs system control macro definitions, so move them
into dt-binding headfile, then include/linux/firmware/imx/types.h can be
removed and those drivers using it should be changed accordingly.

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.

Add SCU PM SVC related protocol definitions which will be used by
a number of PM functions like Power Domain, Clock, Reset and etc.
The detailed implementation of each function will put in the individual
function 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.
