The main goal of this patchset is to remove platform data and replace it by
firmware properties. Original discussion in [1].

While in here, some refactor was done to the driver. The most noticeable one
is to replace the GPIs events handling by irqchip support so that this gpi
keys can be "consumed" by the gpio-keys driver (also as suggested in [1]).
With this, the gpio-adp5588 can be removed. This change comes first so that
we can already remove some platform data variables making it easier to
completly replace it by firmware properties further down in the series.

As there's no users of the platform data, I just replace it in a single
patch as there's no point in having support for both (even though it might
be harder to review the patch as-is).

Special note to the gpio-adp5588 driver removal. I'm aware of some changes
to the driver in [2]. These changes are in the gpio tree and this patchset
is naturally based on the input tree which means that patch 2 will
not apply. So, I'm not really sure how to handle this. I guess in this
case the conflict is easy to handle :) but just let me know on how to
proceed in here if there's anything for me to do.

v2 changes:

[1/10]
 * Turn hwirq signed so we can compare < 0;
 * Replace WARN_ON with dev_warn();
 * Do not set of_node on gpiochip;
 * Moved to use a const irqchip within the gpiochip;
 * Set default handler to 'handle_bad_irq()' and change it
in irq_set_type;

[4/10]
 * Dropped "-keys" from compatible and added vendor prefix;
 * Fix -Wformat complains;
 * Don't use abbrev in comments (fw -> Firmware).

[5/10]
 * Be consistent on $refs;
 * Drop "-keys" from compatible.

[7/10]
 * Include bits.h;
 * Use GENMASK();
 * Use BIT() in KP_SEL();
 * Reflect code changes in the commit message.

[9/10]
 * One line for regulator_disable action.
