V3->V4:
- Made interrupts property compulsory for receiver
- Added interrupts for both nodes in example
- Fixed min/max items for protocols property
- Don't add -tx/rx to node's name.

V2->V3:
- compatible is changed to arm-mhuv2-tx/rx. Later version of MHUv2
  have an interrupt in the sender mode as well and we can't find if a
  mailbox is sender or receiver just based on an interrupt anymore. We
  needed a better way.

- arm-mhuv2-mode is renamed to arm,mhuv2-protocols to fit the purpose
  better.

- Minor formatting otherwise.

Morten: Please let me know if you want me to add your signoff here from
some other email id as you no longer work with ARM.
