Document BCM63xx USBH PHY bindings.

v8: no changes.
v7: introduce changes suggested by Rob:
- Move clock conditions to the main section.
- Set missing additionalProperties to false.
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.
