In subsequent patches we want to allow irqchip drivers to register as
FIQ handlers, with a set_handle_fiq() function. To keep the IRQ/FIQ
paths similar, we want arm64 to provide both set_handle_irq() and
set_handle_fiq(), rather than using GENERIC_IRQ_MULTI_HANDLER for the
former.
Having looked through the series I do not understand this rationale
at all.  You've only added the default_handle_irq logic, which seems
perfectly suitable and desirable for the generic version.  Please
don't fork off generic code for no good reason.
