SCMIv2.0 adds a new Reset Management Protocol to manage various reset
states a given device or domain can enter. Extend the existing SCMI
bindings to add reset protocol support by re-using the reset bindings
for both reset providers and consumers.

arm,scmi.txt used the wrong document identifier. "ARM DUI 0922B" is
the "ARM Compute Subsystem SCP, Message Interface Protocols". What we
need is the ARM DEN 0056A - "ARM System Control and Management
Interface Platform Design Document".
Fixes: fe7be8b297 ("dt-bindings: arm: add support for ARM System Control and Management Interface(SCMI) protocol")

This patch adds devicetree binding for System Control and Management
Interface (SCMI) Message Protocol used between the Application Cores(AP)
and the System Control Processor(SCP). The MHU peripheral provides a
mechanism for inter-processor communication between SCP's M3 processor
and AP.
SCP offers control and management of the core/cluster power states,
various power domain DVFS including the core/cluster, certain system
clocks configuration, thermal sensors and many others.
SCMI protocol is developed as better replacement to the existing SCPI
which is not flexible and easily extensible.
