By using devm_gpiochip_add_data() we can get rid of the
remove() callback. As this driver doesn't use the
gpiochip data pointer we simply pass in NULL.

This makes the code easier to read.

We need to convert all old gpio irqchips to pass the irqchip
setup along when adding the gpio_chip.
For chained irqchips this is a pretty straight-forward
conversion.

The siox driver is hardcoding a default type of
IRQ_TYPE_EDGE_RISING to the irq helper, but this should only
be applicable to old boardfiles and odd device tree irqchips
with just onecell irq (no flags). I doubt this is the case
with the siox, I think all consumers specify the flags they
use in the device tree.

gpiochip_remove() was called on the errorpath if
gpiochip_add() failed: this is wrong, if the chip failed
to add it is not there so it should not be removed.

Reduce driver init boilerplate by using the new
module_siox_driver() macro.

This driver controls a SIOX device that provides 20 I/O lines. The first
twelve are fixed inputs, the remaining eight are outputs.
