mfd: ab8500: provide a irq_set_type() function
In the AB8500 IRQ mask and unmask functions, we rely on testing for IRQ_TYPE_EDGE_RISING and IRQ_TYPE_EDGE_FALLING interrupts to physically mask and unmask the correct interrupt lines. In order for us to do that, the trigger needs to be set in the associated flags. However, unless a irq_set_type() function pointer is passed when registering the IRQ chip, the IRQ subsystem will refuse to do it. For that reason, we're providing one.
