Cristian Marussi 0156ad2a60 firmware: arm_scmi: Fix device node validation for mailbox transport
commit 2ab4f4018c upstream.

When mailboxes are used as a transport it is possible to setup the SCMI
transport layer, depending on the underlying channels configuration, to use
one or two mailboxes, associated, respectively, to one or two, distinct,
shared memory areas: any other combination should be treated as invalid.

Add more strict checking of SCMI mailbox transport device node descriptors.

Fixes: 5c8a47a5a9 ("firmware: arm_scmi: Make scmi core independent of the transport type")
