[PATCH v2 04/15] firmware: imx-dsp: Use mbox_ring_doorbell() instead of NULL message

[Douglas Anderson]

As per the patch ("mailbox: Deprecate NULL mbox messages; Introduce
mbox_ring_doorbell()"), we want to switch all users of NULL mailbox
messages to use mbox_ring_doorbell().

This client only ever sent NULL messages, so the transition is
straightforward.
