[PATCH 3/3] ath79: add support for MikroTik RouterBOARD 911 Lite2/Lite5

[Tomasz Maciej Nowak]

Forward-port from ar71xx target the board introduced in commit
eb9e3651dd1a (" ar71xx: add support for the MikroTik RB911-2Hn/5Hn
boards"). Follow intallation instruction from that commit message, using
images found in ath79 directory. Be advised that the board accepts
10-30 V on PoE input.

Known issues
Compared to ar71xx target image, there is still small leak of current to
user LED, which makes it lit, although weaker, even if brightness is set
to 0. The cause of that is still unknown.
