usb: dwc3-msm: Enable PHY IRQ wakeup only for non-auto targets 



On automotive targets, we do not want the system to wakeup if the
connected peripheral is issuing remote wakeup when the system is
PM suspended. Do not enable the system wakeup capability of the
PHY IRQs if the target is automotive.
