MMC Cards can have an optional Device Tree binding to add non-discoverable properties. Now that we have the DT validation in place, let's convert the device tree bindings for that driver over to a YAML schema. Some of these properties were already described in the MMC controller binding, even though they are not generic and do not apply to any device, so we took the occasion to fix this.
