Convert the OMAP4+ McPDM bindings from txt to yaml (dtschema). Drop ti,hwmods property as it is not needed since the sysc conversion. Add dma, dma-names, reg-names properties to match the DTS so as to not break the already existing ABI. Also update example node to match the existing node in the DTS.
