[PATCH 2/4] Low-level init of hsmmc controller for LogicPD's OMAP3530LV SOM and OMAP 35x Torpedo dev boards

[Jacob Tanenbaum]

From: jake <j...@glados.(none)>

        ARM: OMAP3LOGIC: Adding SDMMC support
             Add low-level initialization for hsmmc controller for
             LogicPD's OMAP 3530 LV SOM and OMAP 35x Torpedo board.

        Tested against: 81e09f50c93edff607259cbe374a3006c9c5fa74
        Signed-off-by: Jacob Tanenbaum <jacob.tanenb...@logicpd.com>
