Subject: [PATCH v3 2/3] ARM/dts: omap3: Add support for IGEPv2 board

ISEE IGEPv2 is an TI OMAP3 SoC based embedded board.

This patch adds an initial device tree support to boot
an IGEPv2 from the MMC/SD.

Currently is working everything that is supported by DT
on OMAP3 SoCs (MMC/SD, GPIO LEDs, EEPROM, TWL4030 audio).

Changes since v1:
    - Use default-state = "on" instead default-trigger = "default-on" for LED
