ARM: kirkwood: Add support for NETGEAR ReadyNAS Duo v2 using DT

Add support for NETGEAR ReadyNAS Duo v2 (Hardware specs available
here: http://natisbad.org/NAS/). Almost everything is supported via
provided .dts. A board-readynas.c file is nonetheless required for
device not only converted to DT (Gbit controller).
