MLK-10237-4 mmc: sdhci-esdhc-imx: add tuning-step setting support
tuning-step is the delay cell steps in tuning procedure. This patch
add the tuning-step setting in driver, so that user can set the
tuning-step value in dts.
e.g.
tuning-step = <2>;
this example set the tuning-step as value 2.
This patch also set the tuning-step of i.MX7D as 2, so that the tuning
procedure can execute successfully.
