[v1,03/13] gpio: dwapb: set default handler to be handle_bad_irq()

We switch the default handler to be handle_bad_irq() instead of
handle_level_irq(), though for now apply it later in the code,
to make the difference between IRQ chips more visible.

s/IRQ chips/IRQ types ?

Note though I'd better refactored the whole dwapb_configure_irqs()
method with using GPIOlib irqchip API, which is preferred by the current
GPIO subsystem. This isn't a subject for this series. Just to note, that
such change is very actual.

Actually IRQ chips. The code instantiates two IRQ chips.

Thanks!

I know, but it's indeed out of scope of this series.
