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).

ARM: dts: omap3-igep0020: Use MMC pwrseq to init SDIO WiFi When the WiFi support was added to the IGEP0020 board, the MMC subsystem did not provide a mechanism to define power sequence providers. So a DT hack was used to toggle the WiFi chip reset and power down pins by using fake fixed regulators whose enable GPIO was the GPIOs connected to these pins. But now the simple MMC power sequence provider can be used for this and the workaround removed.
