ARM: dts: Add support for sbc-3xxx with cm-t3730
This adds support for CompuLab SBC-T3530, also known as cm-t3730: http://compulab.co.il/products/sbcs/sbc-t3530/ It seems that with the sbc-3xxx mainboard is also used on SBC-T3517 and SBC-T3730 with just a different CPU module: http://compulab.co.il/products/sbcs/sbc-t3517/ http://compulab.co.il/products/sbcs/sbc-t3730/ So let's add a common omap3-sb-t35.dtsi and then separate SoC specific omap3-sbc-t3730.dts, omap3-sbc-t3530.dts and omap3-sbc-t3517.dts. I've tested this with SBC-T3730 as that's the only one I have. At least serial, both Ethernet controllers, MMC, and wl12xx WLAN work. Note that WLAN seems to be different for SBC-T3530. And SBC-T3517 may need some changes for the EMAC Ethernet if that's used instead of the smsc911x.
