Convert the driver to immutable irq-chip with a bit of intuition. I switched to consistently using irqd_to_hwirq() consistently while we are at it. As the driver now needs to get the gpio_chip in the .irq_mask and .irq_unmask callbacks, I switched to a pattern where we first fetch the gpio_chip and then the state container from that in two steps. The compiler will do the same thing anyway.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
