[PATCH 4/5] firmware: arm_scmi: smc transport supports multi-message pool

[Etienne Carriere]

There is no reason for the smc transport to restrict itself to a 1
message pool. More can be allocated, messages are copied from/to the
shared memory only on SMC exit/entry hence SCMI driver can play with
several messages.

Use value of 20 to mimic mailbox transport implementation. Any high
value could fit. This should be something configurable.
