mmc: fsl_esdhc_imx: fix the DTOCV to 0xE
On imx6Q/imx6DL, we find if config the DTOCV to 0~3, it will impact
cmd6 behavior, after cmd6 get transfer complete interrupt, the data0
line will keep low over 5 seconds. This should be a IC bug on imx6Q/DL.
For other platforms, do not has this issue.
To fix this issue, fix the DTOCV to 0xE, the max setting, this also align
with Linux configuration.
