When running compliance tests on the Altera Agilex5 SoCFPGA platform, the I3C bus can hang when a slave issues an IBI after the DAA process completes. The DesignWare I3C master enters runtime suspend once DAA finishes and stops driving SCL, preventing the IBI transfer from completing and leaving SDA stuck low. Add a new compatible string, "altr,agilex5-dw-i3c-master" and apply a quirk that keep runtime PM always active on this platform by calling pm_runtime_get_noresume() during probe. Prevent bus hangs triggered by IBIs on Agilex5 while maintaining keep the same behavior on other platforms.

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 reStructuredText 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.
