This adds support for an optional extra interrupt cell to specify edge vs level triggered. It is backward compatible with dts files with only one cell, and will default to level-triggered in such a case. Note that I had to make a change to idu_irq_set_affinity as well, as this function was setting the interrupt type to "level" unconditionally, since this was the only type supported previously.

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.
