Replace the old direct use of platform_device APIs with newer KUnit APIs and the faux bus. The dummy codec driver device doesn't need to be a platform device. It can be a faux bus device. The dummy GPIO driver still must be a platform_device so that a software_node can be added to it before it probes. But use the new KUnit-managed APIs to create the platform_device and platform_driver. These will cleanup automatically when a test completes or fails. Also use KUnit resource cleanup to destroy the faux bus driver and the GPIO software node instead of doing this "manually" in test exit() functions.

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.
