irqdomain: Handle domain bus token in irq_domain_create()
irq_domain_update_bus_token() is the only way to set the domain bus
token. This is sub-optimal as irq_domain_update_bus_token() can be called
only once the domain is created and needs to revert some operations, change
the domain name and redo the operations.
In order to avoid this revert/change/redo sequence, take the domain bus
into account token during the domain creation.
