Frank Li 7597794706 dt-bindings: mmc: Change to additionalProperties to fix fail detect Unevaluated property
mmc-controller.yaml is common schema file. According to writing-schema.rst,

* additionalProperties: true
   Rare case, used for schemas implementing common set of properties. Such
   schemas are supposed to be referenced by other schemas, which then use
   'unevaluatedProperties: false'.  Typically bus or common-part schemas.

Reproduce steps:
1. Add unevaluated property 'abc' at example of fsl-imx-esdhc.yaml
2. Run make dt_binding_check DT_SCHEMA_FILES=fsl-imx-esdhc.yaml

No any warning report. But suppose report below warning:
mmc@70004000: Unevaluated properties are not allowed ('abc' was unexpected)

description:
These properties are common to multiple MMC host controllers. Any host
that requires the respective functionality should implement them using
these definitions.
It is possible to assign a fixed index mmcN to an MMC host controller
(and the corresponding mmcblkN devices) by defining an alias in the
/aliases device tree node.
