Since multiple SMSM hosts are supported, we need to be able to provide the correct mailbox for each host. The old qcom,ipc-N properties map to the mboxes property by index, starting at 0 since that's a valid SMSM host also. Mark the older qcom,ipc-N as deprecated and update the example with mboxes.
