[PATCH v1 6/7] dt-bindings: clock: imx6q: Allow single optional clock and add enet_ref_pad

[Oleksij Rempel <o.rempel@xxxxxxxxxxxxxx>]

All clocks for this driver are optional, so this change allows the
'clocks' and 'clock-names' properties to accept a single clock.
Additionally, 'enet_ref_pad' clock is added. This resolves the following
dtbs_check warning:
  imx6dl-alti6p.dtb: clock-controller@20c4000: clocks: [[24]] is too short
  From schema: Documentation/devicetree/bindings/clock/imx6q-clock.yaml

  imx6dl-alti6p.dtb: clock-controller@20c4000: clock-names:0: 'osc' was
    expected
  From schema: Documentation/devicetree/bindings/clock/imx6q-clock.yaml

    ['enet_ref_pad'] is too short
