dt-bindings: soc: qcom,smsm: Allow specifying mboxes instead of qcom,ipc

Browse source

The qcom,ipc-N properties are essentially providing a reference to a
mailbox, so allow using the mboxes property to do the same in a more
structured way.

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.
