[RFC: WL1271 DC supprot on OMAP3EVM 2/5] ARM: Supported for Standard SDIO driver on OMAP3EVM for WL1271 DC

[csanjay@mistralsolutions.com]

From: Sanjay Kumar Champati <csanjay@mistralsolutions.com>

* Apply MMC2 support patch before apply this patch
* Modified the "Kconfig" and "board-omap3evm.c" files to support
  standard SDIO driver for WL1271 DC
