Kernel now supports chained power-off handlers. Use do_kernel_power_off()
that invokes chained power-off handlers. It also invokes legacy

be converted to the new power-off API.

Judging from an old commit from 2006 [1], this can be rewritten as:
if (!reboot_force && kernel_can_power_off())
machine_shutdown();
do_kernel_power_off();
And maybe later reworked so it doesn't need kernel_can_power_off().
