ENGR00212229 [MX6SL_ARM2]uboot: 8bit MMC cards failed to boot on SD1.
issue:
SD1 connector on ARM2 is an MS-SD combo one which can not make
good contact with DAT4~DAT7 of 8bit mmc cards. It is an hw limitation
which will cause boot failure from 8bit mmc.
solution:
disable SD1 8bit mode on MX6SL arm2 board.
