> For imx usdhc/esdhc, once set the DDR_EN, enable the DDR mode, the

> This will make sure the actual card clock is as our expected.
> IC also suggest config the DDR_EN firstly, then config the clock

> For HS400/HS400ES mode, need to config the strobe dll, this need
> to based on the correct target clock rate, so need to do this after
> clock rate is update.
