PSCI reboot mode will map a mode name to multiple magic values instead of just one. Convert the mode-.* property to an array. Users of the reboot-mode schema will need to specify the maxItems of the mode-.* properties. Existing users will all be 1.

This driver gets the reboot mode magic value from the reboot-mode driver
|
|
and stores it in the NVMEM cell named "reboot-mode". The bootloader can
|
|
then read it and take different action according to the value.
