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".
