mmc: tmio: control multiple block transfer mode
Renesas SDHI has "Multiple Block Transfer Mode" settings
on SD_CMD register which controls CMD12 automatically.
This patch cares it, because
CMD12 is not needed when CMD53 (= SD_IO_RW_EXTENDED)
[Kuninori Morimoto: tidyuped for upstreaming
enabled this flags for all SH-Mobile/R-Car]
