We're planning to remove the gpiochip_add() function to swith
to gpiochip_add_data() with NULL for data argument.

Most interrupt flow handlers do not use the irq argument. Those few
which use it can retrieve the irq number from the irq descriptor.

Remove the argument.

Search and replace was done with coccinelle and some extra helper
scripts around it. Thanks to Julia for her help!

Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc while we
already have a pointer to corresponding irq_desc.

Also replace generic_handle_irq with generic_handle_irq_desc() to avoid
looking up irq_desc again.

this remove all reference to gpio_remove retval in all driver
except pinctrl and gpio. the same thing is done for gpio and
pinctrl in two different patches.

In the interest of getting off of the create_irq() API we can get all of
the functionality we're interested in through a linear IRQ domain. Fairly
straightforward conversion utilizing a single linear domain.

Checks for (irq < 0) and (ilsel < 0) didn't make sense since they were
unsigned.  Made them signed.

This adds trivial support for the GPIOs implemented through the baseboard
CPLD, used for driving the button matrix.
