ARM: dts: Add devicetree for NovaTech OrionLXm

This adds the NovaTech OrionLXm which is based on the AM335x SoC
http://www.novatechweb.com/substation-automation/orionlxm/

RAM: 512MiB
Flash: 4GB eMMC
Ethernet PHYs: 2x Micrel KSZ8041FTLI
USB ports are used internally by the expansion cards.
Internal micro SD slot is available.
