usb: dwc3: qcom: fix missing optional irq warnings

[ Upstream commit 69bb3520db7cecbccc9e497fc568fa5465c9d43f ]

Not all platforms have all of the four currently supported wakeup
interrupts so use the optional irq helpers when looking up interrupts to
avoid printing error messages when an optional interrupt is not found:

	dwc3-qcom a6f8800.usb: error -ENXIO: IRQ hs_phy_irq not found
