Currently not all of the Port-specific capabilities listed in the PORT_CMD-enumeration. Let's extend that set with the Cold Presence Detection and Mechanical Presence Switch attached to the Port flags [1] so to closeup the set of the platform-specific port-capabilities flags. Note these flags are supposed to be set by the platform firmware if there is one. Alternatively as we are about to do they can be set by means of the OF properties. While at it replace PORT_IRQ_DEV_ILCK with PORT_IRQ_DMPS and fix the comment there. In accordance with [2] that IRQ flag is supposed to indicate the state of the signal coming from the Mechanical Presence Switch.

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.
