From: Peng Fan <peng.fan@nxp.com>
Add i.MX SCMI Extension protocols bindings for:
- Battery Backed Module(BBM) Protocol
This contains persistent storage (GPR), an RTC, and the ON/OFF button.
The protocol can also provide access to similar functions implemented via
external board components.
- MISC Protocol.
This includes controls that are misc settings/actions that must be exposed
from the SM to agents. They are device specific and are usually define to
access bit fields in various mix block control modules, IOMUX_GPR, and
other GPR/CSR owned by the SM.
