dom0less: Turn arch_create_domUs into arch_parse_dom0less_node()

It deals with a single domain, and will be called on a later patch
by a new function parse_dom0less_node(), so the new name is apt.

Also, pass parameters using boot_domain instead as the plan is to use it
as dumping gound for all the extracted information from the bindings.

Not a functional change.
