mmc: tmio: bus_shift become tmio_mmc_data member

Browse Source 
.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.
