Subject: [PATCH 1/3] dt-bindings: mmc: imx-esdhc: Change imx8mn and imx8mp compatible fallback

The SDHC controller in the imx8mn and imx8mp have the same controller
as the imx8mm which is slightly different than that of the imx7d.
Using the fallback of the imx8mm enables the controllers to support
HS400-ES which is not available on the imx7d.
