Resending with updated recepients and cover subject.

PM8150 uses reboot-mode framework to set magic values for bootloader to read
during next boot. dm-verity wants to use "dm-verity device corrupted" [1] as
the restart command, however the reboot-mode framework does not support spaces
in the command line as devicetree property names cannot have spaces. In order
to support the PM8150 comamnds, this patch series adds two new optional array
properties to reboot-mode framework: reboot-mode-names and reboot-mode-magic.
The arrays supply the commands and magic values, respectively.
