Sorry, we didn't know about the SMC transport support for SCMI. Looks
like it was added only recently, while our driver was already developed
and waiting to be upstreamed.

I agree that we can drop this driver and switch to the SMC transport as
you suggested, but I think we'll have to modify our bootloader SiP
service slightly. Paul, can you elaborate?
