[RFC PATCH 0/4] Implement a PSCI SYSTEM_RESET2 reboot-mode driver

[Elliot Berman]

PSCI implements a restart notifier for architectural defined resets.
The SYSTEM_RESET2 call allows vendor firmware to define additional reset
types which could be mapped to the reboot reason.

Implement a driver to wire the reboot-mode framework to make vendor
SYSTEM_RESET2 calls on reboot.

This is a continuation from https://lore.kernel.org/all/4a679542-b48d-7e11-f33a-63535a5c68cb@quicinc.com/
