Analogix 7625 can be used in systems to switch USB Type-C DisplayPort alternate mode lane traffic between 2 Type-C ports.
Update the binding to accommodate this usage by introducing a switch property.

Changes since v3: - Fix unevaluatedProperties usage. - Add additionalProperties to top level "switches" nodes. - Make quotes consistent. - Add '^..$' to regex. (All suggested by Krzysztof Kozlowski)
Changes since v2: - Added Reviewed-by and Tested-by tags.
Changes since v1: - Introduced patternProperties for "switch" children (suggested by Krzysztof Kozlowski). - Added unevaluatedProperties descriptor (suggested by Krzysztof Kozlowski). - Added "address-cells" and "size-cells" properties to "switches".
