dt-bindings: mmc: convert synopsys dw-mshc bindings to yaml
Current dts files with 'dwmmc' nodes are manually verified. In order to automate this process synopsys-dw-mshc.txt has to be converted to yaml. In the new setup synopsys-dw-mshc.yaml will inherit properties from mmc-controller.yaml and synopsys-dw-mshc-common.yaml. 'dwmmc' will no longer be a valid name for a node and should be changed to 'mmc'.
