Update remove_dma_window() so it can be used to remove DDW with a given property name. This enables the creation of new property names for DDW, so we can have different usage for it, like indirect mapping. Also, add return values to it so we can check if the property was found while removing the active DDW. This allows skipping the remaining property names while reducing the impact of multiple property names.

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.
