Changes in v2:
- Changed MAINTAINERS to "Kishon Vijay Abraham".
- Renamed the YAML file name to "ti,omap2430-sdhci.yaml" from
  "sdhci-omap.yaml".
- Dropped unnecessary or unused properties from DTS and made these
  changes as a seperate commit as there is no user of it.
- Removed previously defined properties like ti,needs-special-reset,
  ti,needs-special-hs-handling and cap-mmc-dual-data-rate from the YAML.
- Changed the commit message to elaborate the reasons for modifications.
- Removed the pattern property for pinctrl and redefined it in a regular format.
- Modified the description of the property "clock-frequency".
- Changed the subject line for the binding patch.
