genirq: introduce irq_domain_translate_twocell

Browse source

Add a new function irq_domain_translate_twocell() that is to be used as
the translate function in struct irq_domain_ops for the v2 IRQ API.

This patch also changes irq_domain_xlate_twocell() from the v1 IRQ API
to call irq_domain_translate_twocell() in the v2 IRQ API. This required
changes to of_phandle_args_to_fwspec()'s arguments so that it can be
called from multiple places.
