Add support for LED hw control for the netdev trigger. The trigger on calling set_baseline_state to configure a new mode, will do various check to verify if hw control can be used for the requested mode in can_hw_control() function. It will first check if the LED driver supports hw control for the netdev trigger, then will use hw_control_is_supported() and finally will call hw_control_set() to apply the requested mode. To use such mode, interval MUST be set to the default value and net_dev MUST be set. If one of these 2 value are not valid, hw control will never be used and normal software fallback is used. The default interval value is moved to a define to make sure they are always synced.

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.
