This patch series converts i.MX and MXS mmc binding to json-schema,
fix some minor issues in original binding doc, such as node name should be 'mmc',
compatible name for i.MX27, reg/interrupts should be required properties etc..
Compared to V1, this patch series adds "unevaluatedProperties: false" for
each binding doc.
