[0/3] Add SCMI Vendor module autoload support

Message

Hi,

a tiny series to add the capability to automatically load the proper
vendor protocol module when an SCMI driver tries to use it; while proper
vendor protocol selection is already provided by the SCMI core, automatic
loading of vendor protocols was not.

Lookup is now based on module aliases following the pattern:

	scmi-protocol-0x<PROTO_ID_NN>-<VENDOR_ID>

In [2/2] proper aliases are added to existing i.MX Vendor protocols...
...could not find a better way to build the alias string automagically...
...any advice is welcome in these regards...and any feedback too !

In V2, an additional patch is added to simply add the proper/required
MODULE_DEVICE_TABLE to SCMI transport driver to enable autoloading also
for those.

Thanks,
Cristian

V1 --> V2
- added tags
- added Transport aliases patch via MODULE_DEVICE_TABLE
