[PATCH V2 1/4] ARM: dts: imx6sll: Update usdhc fallback compatible to support HS400 mode

[Anson Huang]

The i.MX6SLL SoC can support HS400 mode, hence "fsl,imx7d-usdhc"
should be used as compatible string to support HS400 mode by
default.

Since this is a dtsi patch, it is better not to mention a specific
board here in the commit log.

It would be better to say that unlike i.MX6SL, the i.MX6SLL SoC can
support HS400 mode, hence fsl,imx7d-usdhc should be used as compatible
string.
