ath79: WNR612v2: improve device support

This patch improves ath79 support for Netgear WNR612v2.
Router functionality becomes identical to ar71xx version.

Changes include:
* software control over LAN LEDs via sysfs
* correct MAC addresses for network interfaces
* correct image size in device definition
* dts: 'keys' renamed to 'ath9k-keys'
* dts: 'label-mac-device' set to eth1 (LAN)
* dts: formatting adjustments
