Add LEDs support for qca8k Switch Family. This will provide the LEDs
hardware API to permit the PHY LED to support hardware mode.
Each port have at least 3 LEDs and they can HW blink, set on/off or
follow blink modes configured with the LED in hardware mode..
This adds support for 2 hardware trigger netdev and
hardware-phy-activity.
