Add board specific devicetree for Bananapi R3 SBC.

Signed-off-by: Daniel Golle daniel@makrotopia.org Signed-off-by: Frank Wunderlich frank-w@public-files.de --- taken from openwrt https://git.openwrt.org/?p=openwrt/openwrt.git;a=blob;f=package/boot/uboot-m... only enabled the factory button which was disabled because a HW-bug in rev 1.0 of r3.
