Check types_supported instead of checking type_rising/falling_val when using type_in_mask interrupts. This makes the intent clearer and allows a type_in_mask irq to support level or edge triggers, rather than only edge triggers. Update the documentation and comments to reflect the new behavior. This shouldn't affect existing drivers, because if they didn't set types_supported properly the type buffer wouldn't be updated.

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.
