The core irq_set_type() function updates the flow type when the chip
callback returns 0. So setting the type is bogus.
The new core code allows to update the type in irq_data and return
IRQ_SET_MASK_OK_NOCOPY, so the core code will not touch it, except for
setting the IRQ_LEVEL flag.
Use the proper accessors for setting the irq handlers.
