omap3: cm-t3517: add basic board support

CompuLab cm-t3517 is Computer on Module (CoM) based on AM3517 SoC.
Features: up to 256MB DDR2, up to 512MB NAND, USB hub, mUSB, WiFi, BT,
Analog audio codec, touch screen controller, LED.

Add basic support including:
LED, Serial console, NAND, MMC, GPIO, I2C, 256MB DRAM.
