mmc: tmio: bus_shift become tmio_mmc_data member
.bus_shift is used to 16/32bit register access offset calculation on tmio driver. tmio_mmc_xxx is used from Toshiba/Renesas now, but this bus_shift value depends on HW IP. This patch moves .bus_shift to tmio_mmc_data member and sets it on each driver. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Chris Ball <cjb@laptop.org>
