 v6: introduce changes suggested by Rob:
  - Add another if case to device tree binding for SoCs with just 1 clock.
  - Ignored "additionalProperties: false" suggestion since it triggers a
    warning. This has been reported, but I haven't received any answer yet.
 v5: no changes.
 v4: conditionally require 1/2 clocks and fix clock/reset values.
 v3: no changes.
 v2: phy-cells changed to 1.
