The richtek,rt1711h binding has a legacy plain-text file that was
superseded by the YAML schema. Remove it.

The YAML schema also declares 'additionalProperties: false' but
omits the top-level 'port' property used by hi3660-hikey960.dts
to describe the role-switch graph endpoint, causing dtbs_check
to emit:

  hi3660-hikey960.dtb: rt1711h@4e (richtek,rt1711h): 'port' does
  not match any of the regexes: '^pinctrl-[0-9]+$'

Add the missing property referencing /schemas/graph.yaml.

A separate dtbs_check warning on the same node is out of scope
for this series:

  hi3660-hikey960.dtb: rt1711h@4e (richtek,rt1711h):
  connector:ports: 'port@0' is a required property

That one is in the connector subnode and is governed by
usb-connector.yaml, not this binding.
