Add support for CM-T3517 CoM and SBC-T3517 board.
reused common support for sbc-t3x boards
(omap3-cm-t3x.dtsi, omap3-sb-t35.dtsi):
* SB-T35 baseboard eth
* MMC1, UART3
* HS USB Port 1/2
* I2C1/3
* Heartbit led
Added basic support for:
* MMC1 wp/cd signals
* CM-T3517 Usb Hub
* WL12xx WiFi chip
* Davinci EMAC
* AM35X OTG
