Subject: [PATCH v3] dt-bindings: mmc: fsl-imx-esdhc: Add some compatible fallbacks

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

Add fallbacks for imx6sll/ull which are useful for U-Boot.

This will significantly reduce noise on make dtbs_check.

Signed-off-by: Andreas Kemnade <andreas@...nade.info>
---
Changes in v3:
- simplify things by using enums

Changes in v2:
- allow only combinations with fallback compatible
- reduce them to the cases where they are actually useful
