[Peng Fan (OSS)]

i.MX95 System Manager Firmware support vendor extension protocol:
- Battery Backed Module(BBM) Protocol for RTC and BUTTON feature.
- MISC Protocol for misc settings, such as BLK CTRL GPR settings, GPIO
expander settings.

This patchset is to support the two protocols and users that use the
protocols.
