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.

Hello,

Some features like WLAN/BT, HDMI and LCD support for VAR-DVK-OM44 is missing
from this patch set.

WLAN/BT could be fixed by adding some code to pdata-quirks.c but I'll rather
wait for proper DT bindings.

The OM44CustomBoard has a HDMI port but uses a different tranceiver than the
Panda board. So I guess it will need a new driver.

I will eventually add HDMI support and VAR-DVK-OM44 LCD support.

best regards
Joachim Eastwood
