[PATCH] arm: mvebu: support for the PlatHome OpenBlocks AX3 board

[Thomas Petazzoni]

This platform, available in Japan from PlatHome, has a dual-core
Armada XP, the MV78260. For now, only the two serial ports and the
three front LEDs are supported. Support for network, SATA, USB and
other peripherals will be added as drivers for them become available
for Armada XP in mainline.
