Port_sts is a thing of the past for this driver. It was something present on the initial implementation of this driver and parts of the original struct were dropped over time. Using an array of int to store if a port is enabled or not to handle PM operation seems overkill. Switch and use a simple u8 to store the port status where each bit correspond to a port. (bit is set port is enabled, bit is not set, port is disabled) Also add some comments to better describe why we need to track port status.

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.
