[PATCH v2 0/2] dt-bindings: mmc: st,sdhci: convert STMicroelectronics SDHCI-ST MMC/SD Controller controller binding to YAML

This patch series converts the legacy text-based Device Tree binding for
STMicroelectronics SDHCI-ST MMC/SD controller to DT schema (YAML) format.

Note:
The patch "dt-bindings: mmc: st,sdhci: convert to DT schema"
depends on the patch "arm: dts: st: align node patterns with established
convention". If the DT schema patch is applied before the DTS
cleanup patch, `dtbs_check` will fail due to the presence of the removed
properties in the existing DTS.

Changes in v2:
- Fix node name in DTS for the MMC to match with the estableshed convention.
- st,sdhci: drop unnecessary properties, modify "reg", "reg-names" and
"clock-names" properties, include an allOf with $ref to mmc-controller.
- Link to v1: https://patch.msgid.link/20260409-st-mmc-v1-1-4c54321c3535@gmail.com
