I may say something obvious but, looking at the kernel log, it seems to me
that it is the SCMI subsystem as a whole that is never initialized and goes
through a lot of deferrals because its only transport, the brcmstb-mbox, is
in turn never found to be ready, then as a consequence your serial, relying
on scmi-clock, is never initialized too.

In JUNO in fact I can see the same pattern of deferrals during boot (if I
enable dev_info in dev_link) until the ARM MHU mailboxes are found and
initialized and then firmware:scmi stops being deferred and it is
initialized with all the stack and its consumers.

I cannot see the brcm_scmi_mailbox@0 being found here instead.

Thanks

Cristian
