But these are copied from sh_mobile_sdhi only, and sh_mobile_sdhi_info is now almost same as tmio_mmc_data except .chan_priv_?x. sh_mobile_sdhi_info can be replaced to tmio_mmc_data, but it is used from ${LINUX}/arch/arm/mach-shmobile, ${LINUX}/arch/sh. So, this patch adds .chan_priv_?x into tmio_mmc_data as 1st step, and sh_mobile_sdhi driver has dummy operation for now. It will be replaced/removed together with platform data replace.
