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.

Fixes: 1ed5c3b22fc7 ("mmc: sdhci-esdhc-imx: Propagate ESDHC_FLAG_HS400* only on 8bit bus")
