> After commit 1ed5c3b22fc7 ("mmc: sdhci-esdhc-imx: Propagate
> ESDHC_FLAG_HS400* only on 8bit bus"), the property "no-mmc-hs400"
> from device tree file do not work any more.
> This patch reorder the code, which can avoid the warning message "drop HS400
> support since no 8-bit bus" and also make the property "no-mmc-hs400" from
> dts file works.
