Subject: [PATCH] irqdomain: export irq_domain_simple_ops for !CONFIG_OF

irqdomain support is used in interrupt controller drivers that may not
have device tree support but only need the basic HW->Linux irq
translation.  Rather than having each of these implement their own IRQ
domain, allow them to use the simple ops.
