ARM: dts: Add support for OMAP4 Variscite OM44 family

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.
