Convert the driver to immutable irq-chip with a bit of
intuition.
Whereas in most cases we put the gpiochip_[enable|disable]_irq()
calls in the .irq_mask() and .irq_unmask() callbacks, here
we need to put them in the .irq_enable() and .irq_disable()
callbacks, as this driver uses both .irq_mask() and
.irq_mask_ack().

Convert the driver to immutable irq-chip with a bit of
intuition.
In this case I had to figure out a way to get to the
struct gpio_chip that would work even when the irq_chip
is not part of the driver state container. I did this by
just doing what most other GPIO drivers do and pass
the state struct as data to devm_gpiochip_add_data()
and rewrite accordingly.

There is no need to manually set the owner of a struct class, as the
registering function does it automatically, so remove all of the
explicit settings from various drivers that did so as it is unneeded.
This allows us to remove this pointer entirely from this structure going

Add minimal driver for Fairchild FXL6408 8-bit I2C-controlled GPIO expander
using the generic regmap based GPIO driver (GPIO_REGMAP).
The driver implements setting the GPIO direction, reading inputs
and writing outputs.
In addition to that the FXL6408 has the following functionalities:
- allows to monitor input ports for data transitions with an interrupt pin
- all inputs can be configured with pull-up or pull-down resistors

Convert the driver to immutable irq-chip with a bit of
intuition.
This driver require some special care: .irq_ack() was copied
from dummy_irq_chip where it was defined as noop. This only
makes sense if using handle_edge_irq() that will unconditionally
call .irq_ack() to avoid a crash, but this driver is not ever
using handle_edge_irq() so just avoid assigning .irq_ack().
A separate chip had to be created for the non-wakeup instance.
