Subject: [PATCH v7 1/5] dt-bindings: power: reset: Convert mode-.*
 properties to array

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.
