[0/4] Add restart commands for PM8150

Message

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. 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.
