Add devm_irq_domain_create_linear() as the devres-managed sibling of irq_domain_create_linear(): it builds the same linear-revmap irq_domain_info and hands it to devm_irq_domain_instantiate(), so the domain is removed when the owning device is unbound. The return convention matches irq_domain_create_linear() (NULL on failure).
