mailbox: pcc: Notify clients on polled completion

Browse source

PCC channels without a platform interrupt rely on the mailbox
polling path to detect command completion.

That path currently only reports transmit completion to the mailbox
core, so clients that wait for their receive callback do not get
notified when the command completes.

Call mbox_chan_received_data() when polling observes completion on a
channel without a platform IRQ, matching the interrupt-driven
completion path.
