[PATCH 04/15] firmware: arm_scmi: Add names to scmi devices created

[Sudeep Holla <sudeep.holla@arm.com>]

Now that scmi bus provides option to create named scmi device, let us
create the default devices with names. This will help to add names for
matching to respective drivers and eventually to add multiple devices
and drivers per protocol.
