mmc: sdhci-esdhc-imx: Select the correct mode for auto tuning
USDHC hardware auto tuning circuit support check 1/4/8 data lines and cmd
line. Out of reset uSDHC, it default select check 4 data lines and do not
check cmd line. This is incorrect if we use 8 data lines. So need to config
the auto tuning mode according to current bus width.
