irq_domain: Create common xlate functions that device drivers can use
Rather than having each interrupt controller driver creating its own barely unique .xlate function for irq_domain, create a library of translators which any driver can use directly. v5: - Remove irq_domain_xlate_pci(). It was incorrect.
