Patch 1 of this series implements the restart handler function. Patches 2 and 3
implement calling the restart handler chain from arm and arm64 restart code.

Patch 4 modifies the restart-poweroff driver to no longer call arm_pm_restart
directly but machine_restart. This is done to avoid calling arm_pm_restart
from more than one place. The change makes the driver architecture independent,
so it would be possible to drop the arm dependency from its Kconfig entry.

Patch 5 and 6 convert existing restart handlers in the watchdog subsystem
to use the restart handler. Patch 7 unexports arm_pm_restart to ensure
that no one gets the idea to implement a restart handler as module.

For the current patches:

Do you plan to convert more of the power/drivers/reset/ code?

BTW, is it worth doing something similar for pm_power_off (there is
generic code calling it directly, so slightly more complicated than
pm_restart)?
