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.

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.
