[U-Boot] [PATCH] ARM: omap3: overo: Fix MMC init for SPL

[anselm.busse at outlook.com]

From: Anselm Busse <anselm.busse at outlook.com>

The SPL for the Overo board does not initialise the MMC. Hence, it cannot load the main boot loader from the SD card susequently. This Patch moves the initialisation code for the MMC so it gets included in the SPL.
