mmc: au1xmmc command types check from data flags
This patch has changed command types check from data flags. MMC_STOP_TRANSMISSION is never passed to au1xmmc_send_command(). SEND_STOP() is used for MMC_STOP_TRANSMISSION. Signed-off-by: Yoichi Yuasa <yoichi_yuasa@tripeaks.co.jp> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
