dt-bindings: zynqmp: add destination mailbox compatible
Current dt-bindings does not contain compatible property for child mailbox node. Child mailbox nodes are used to represent destination (remote) IPI agents. The compatible property for all destination mailboxes must be required to identify the node. This addition of new required property does not break ABI as current driver does not use this compatible property but, new features in driver should use this property.
