net: dsa: hellcreek: Add PTP status LEDs
The switch has two controllable I/Os which are usually connected to LEDs. This is useful to immediately visually see the PTP status. These provide two signals: * is_gm This LED can be activated if the current device is the grand master in that PTP domain. * sync_good This LED can be activated if the current device is in sync with the network time. Expose these via the LED framework to be controlled via user space e.g. linuxptp.
