[PATCH 0/3] riscv: sbi: Switch to the sys-off handler API

[Samuel Holland]

I want to convert the axp20x PMIC poweroff handler to use the sys-off
API, so it can be used as a fallback for if the SBI poweroff handler
is unavailable. But the SBI poweroff handler still uses pm_power_off, so
done alone, this would cause the axp20x callback to be called first,
before the SBI poweroff handler has a chance to run.

In order to prevent this change in behavior, the SBI poweroff handler
needs to be converted to the sys-off API first, at a higher priority.

This series performs the conversion, after accounting for the fact that
the SBI poweroff handler is registered quite early during boot.

The first patch is a dependency for both this series and the PSCI
series[1], so I would like to get at least patch 1 merged soon.
