firmware: arm_scmi: Add support for multiple vendors custom protocols

Browse source

Add a mechanism to be able to tag vendor protocol modules at compile-time
with a vendor/sub_vendor string and an implementation version and then to
choose to load, at run-time, only those vendor protocol modules matching
as close as possible the vendor/subvendor identification advertised by
the SCMI platform server.

In this way, any in-tree existent vendor protocol module can be build and
shipped by default in a single kernel image, even when using the same
clashing protocol identification numbers, since the SCMI core will take
care at run-time to load only the ones pertinent to the running system.
