Add LEDs basic support for qca8k Switch Family by adding basic
brightness_set() support.

Since these LEDs refelect port status, the default label is set to
":port". DT binding should describe the color, function and number of
the leds using standard LEDs api.

These LEDs supports only blocking variant of the brightness_set()
function since they can sleep during access of the switch leds to set
the brightness.

While at it add to the qca8k header file each mode defined by the Switch
Documentation for future use.

Hi Christian,

The patch looks good to me. I just found one nitpick in the comment.

Thanks,
Michal

Nitpick: "at least" -> "at most"
