An empty snps,quirk-frame-length-adjustment won't cause any change
performed by the driver. Moreover the DT schema validation will fail,
since it expects the property being assigned with some value. So set
fix the example by setting a valid FL-adj value in accordance with
Neil Armstrong comment.

Note the same problem is in the DT source file

Amlogic G12A USB DT sub-nodes are supposed to be compatible with the
generic DWC USB2 and USB3 devices. Since now we've got DT schemas for
both of the later IP cores let's make sure that the Amlogic G12A USB
DT nodes are fully evaluated including the DWC sub-nodes.

Changelog v2:
- Use "oneOf: [dwc2.yaml#, snps,dwc3.yaml#]" instead of the bulky "if:
properties: compatibe: ..." statement.
