soc/intel/xeon_sp: Add ACPI names

Set the unused 'name' property of the domain device and store
the ACPI name. Every IIO stack can have multiple domain devices,
each owning a subset of the available bus range within the stack.

The name will be used in future changes to generate ACPI names
in SSDT code generation. It can also be used to identify the domain
type by looking at the first two characters of the name.
