Subject: [PATCH V3 0/4] Fixup fsl-imx-ehci fallback

The imx8mm-usdhc is a superset of the imx7d-usdhc which adds
HS400-ES.
The i.MX8MN and i.MX8MP both support the HS400-ES so the fallback
to imx8mm-usdhc is more correct since they share the same IP block
as the imx8mm.  This series updates the YAML file to show the updated
compatible fallbacks while keeping the older imx7d-usdhc to prevent
breakage and keep backwards compatibility. However, a note was added
indicating the imx7d fallback was deprecated for certain devices.
It then updates the imx8mn and imx8mp to fallback to both imx8mm and
imx7d to enable the missing HS400-ES functionality.

  dt-bindings: mmc: imx-esdhc: Update compatible fallbacks
