gpio: adp5585: support gpi events
Add support for adding GPIs to the event FIFO. This is done by adding
irq_chip support. Like this, one can use the input gpio_keys driver as a
"frontend" device and input handler.
As part of this change, we now implement .request() and .free() as we can't
blindly consume all available pins as GPIOs (example: some pins can be
used for forming a keymap matrix).
Also note that the number of pins can now be obtained from the parent,
top level device. Hence the 'max_gpio' variable can be removed.
