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.

This is done via RPC call to SCU.

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.

firmware: imx: remove resource id enums2018-11-14T01:20:38+00:00A.s. Dongaisheng.dong@nxp.com2018-11-01T15:19:58+00:00urn:sha1:3501ce96bf5d9dd8563dd94595436d3757ec817e
We already export resource id in dt-bindings headfile which can also
be used by drivers. So no need keep the same definitions in regular
headfile anymore.

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.
