Parade PS5511 is USB hub with 4 USB 3.2 compliant 5Gbps downstream(DS)
ports, and 1 extra USB 2.0 downstream port. The hub has one reset pin
control and two power supplies (3V3 and 1V1).

Signed-off-by: Pin-yen Lin <treapking@chromium.org>

Changes in v2:
- Inherit usb-hub.yaml
- Fix bindings to reject port@5/device@5 for 3.0 hub correctly
- Minor string fixes
