The OF LED configuration patch fails on MT7621, as the necessary headers
were only included for the mediatek subtarget with an additional patch.

This adds a small hack similar to the one used for ar8xxx switches to
read a reg:value map for configuring the LED configuration registers.
This allows OpenWrt to write device-specific LED action as well as blink
configurations. It is unlikely to be accepted upstream, as upstream
plans on integrating their own framework for handling these LEDs.
