Subject: [PATCH] dt-bindings: mmc: fsl-imx-esdhc: allow more compatible combinations

Currently make dtbs_check shows lots of errors because imx*.dtsi does
not use single compatibles but combinations of them.
Allow all the combinations used there.

Patches fixing the dtsi files according to binding documentation were
submitted multiple times and are commonly rejected, so relax the rules.
Example:
https://lore.kernel.org/linux-devicetree/72e1194e10ccb4f87aed96265114f0963e805092.camel@pengutronix.de/

Reason: compatibility of new dtbs with old kernels or bootloaders.

This will significantly reduce noise on make dtbs_check.
