[PATCH v2] dt-bindings: mmc: Convert TI OMAP2420 MMC to DT schema

[PATCH v2] dt-bindings: mmc: Convert TI OMAP2420 MMC to DT schema

[Eduard Bostina]

Convert the Texas Instruments MMC host controller bindings
to DT schema.

Note that the OMAP2420 driver will not work with OMAP2430 or later omaps.
Please see the OMAP HSMMC driver for current OMAPs.

Changes in v2:
  - Changed ti,hwmods type reference from string-array to string
  - Updated ti,hwmods regex pattern to "^msdi([1-9]|[1-9][0-9]+)$"
