Subject: [PATCH 18/23] irqdomain: Convert domain creation functions to irq_domain_instantiate()

Domain creation functions use __irq_domain_add(). With the introduction
of irq_domain_instantiate(), __irq_domain_add() becomes obsolete.

In order to fully remove __irq_domain_add(), convert domain
creation function to irq_domain_instantiate()
