dt-bindings: usb: qcom,dwc3: Correct MSM8994 interrupts

According to the reference manual, MSM8994 does have QUSB2 PHY and does
not have DP/DM IRQs interrupts.  It is also logical it has the same
constraints as similar device: MSM8996.

This fixes dtbs_check warnings like:

  msm8994-sony-xperia-kitakami-karin.dtb: usb@f92f8800 (qcom,msm8994-dwc3): interrupt-names:1: 'hs_phy_irq' was expected
  msm8994-sony-xperia-kitakami-karin.dtb: usb@f92f8800 (qcom,msm8994-dwc3): interrupt-names:2: 'dp_hs_phy_irq' was expected
  msm8994-sony-xperia-kitakami-karin.dtb: usb@f92f8800 (qcom,msm8994-dwc3): interrupt-names:3: 'dm_hs_phy_irq' was expected

Fixes: 53c6d854be4e ("dt-bindings: usb: dwc3: Clean up hs_phy_irq in binding")
Fixes: 6e762f7b8edc ("dt-bindings: usb: Introduce qcom,snps-dwc3")
