dt-bindings: usb: qcom,dwc3: Update ipq5332 interrupt info

IPQ5332 has only three interrupts. Update the constraints
to fix the following dt_binding_check errors.

	interrupt-names: ['pwr_event', 'dp_hs_phy_irq', 'dm_hs_phy_irq'] is too short

Fixes: 53c6d854 ("dt-bindings: usb: dwc3: Clean up hs_phy_irq in binding")
