arm64: dts: hisilicon: hi3660-hikey960: move role-switch endpoint into connector

Browse Source 
The rt1711h Type-C controller on the HiKey960 has the USB role-switch
endpoint placed as a top-level 'port' node, outside the connector
subnode. This triggers two dtbs_check warnings against
richtek,rt1711h.yaml:

  - 'port' does not match any of the regexes: '^pinctrl-[0-9]+$'
  - connector:ports: 'port@0' is a required property

Move the role-switch endpoint into the connector's port@0, which is
where usb-connector.yaml expects it. Update the DWC3 remote-endpoint
phandle accordingly.

The TCPM core (tcpm.c) looks up the role switch starting from the
connector fwnode via fwnode_usb_role_switch_get(). With the endpoint
inside the connector's port@0, it is found through the primary lookup
path rather than the device-level fallback.

Cross-compiled for arm64. Verified with dt_binding_check and
dtbs_check. Not runtime-tested on hardware.
