From: Lee Jones <lee.jo...@linaro.org>
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.

Sam, it'd be nice if you could ACK these first four patches,
the series basically simplifies things a lot by not cascading
the AB8500 IRQs and duplicate code in the pinctrl driver.
