[2/7] dt-bindings: usb: qcom,dwc3: refine interrupt requirements

Not all platforms have all of the four wakeup interrupts currently
described by the bindings.

Specifically, MSM8953/6/8 and SDM660 do not use the DP/DM interrupts,
while the SS PHY interrupt is optional on SDM660 and SC7280.

Note that no devicetree in mainline specify any wakeup interrupts for

  - qcom,ipq4019-dwc3
  - qcom,ipq6018-dwc3
  - qcom,ipq8064-dwc3
  - qcom,ipq8074-dwc3
  - qcom,msm8994-dwc3
  - qcom,qcs404-dwc3

but let's keep the schema warnings about that for now.

OK, I see now that you used SC8280XP order matching this one.
