[ARM] OMAP: Fix MMC device data

OMAPs MMC device data was passing the wrong structure via the platform
device.  Moreover, a missing function means that both sx1_defconfig
and omap_h2_1610_defconfig builds failed with

	undefined reference to `omap_set_mmc_info'

errors.  Fix this by updating the MMC support from the omapzoom tree.
