I am happy with the changes in the series, they all look good. I wonder if
it makes sense to move transport drivers into a separate folder
drivers/firmware/arm_scmi/transport/{mailbox,smc,optee,virtio}.c

In scmi_transport_*.c, I see scmi is redundant and transport can be eliminated
by moving all under the folder with that name. Thoughts ?
