[PATCH 2/2] dt-bindings: phy: qcom,sc7180-qmp-usb3-dp-phy: correct clocks per variants

Different variants of Qualcomm USB3 DP PHY take different clocks
(according to upstream DTS and Linux driver):

  sc7280-herobrine-crd.dtb: phy-wrapper at 88e9000: clocks: [[43, 151], [39, 0], [43, 153]] is too short
  sc7280-herobrine-crd.dtb: phy-wrapper at 88e9000: clock-names:1: 'cfg_ahb' was expected
  ...
  sm8250-hdk.dtb: phy at 88e9000: clocks: [[46, 185], [44, 0], [46, 187]] is too short
  sm8250-hdk.dtb: phy at 88e9000: clock-names:1: 'cfg_ahb' was expected
