Add support for VAR-SOM-OM44[1] SODIMM system on module from Variscite. SoM features a OMAP4460, 1GB RAM, Gigabit Ethernet (LAN7500) and optional WLAN/BT. Also add support for VAR-STK-OM44 development board from Variscite. This kit features a VAR-SOM-OM44 and the carrier board VAR-OM44CustomBoard[2]. The VAR-STK-OM44 is the same as VAR-DVK-OM44 but without the LCD display. omap4-var-stk-om44.dts replace the old and very limited omap4-var-som.dts.
