[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. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
