Add support for PHY LEDs polarity modes. Some PHY require LED to be set to active low to be turned ON. Adds support for this by declaring active-low property in DT. PHY driver needs to declare .led_polarity_set() to configure LED polarity modes. Function will pass the index with the LED index and a bitmap with all the required modes to set. Current supported modes are: - active-low with the flag PHY_LED_ACTIVE_LOW. LED is set to active-low to turn it ON. - inactive-high-impedance with the flag PHY_LED_INACTIVE_HIGH_IMPEDANCE. LED is set to high impedance to turn it OFF.

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.
