usb: dwc3: core: Suspend PHYs on runtime suspend in host mode
Some PHY drivers (e.g. for Qualcomm QUSB2 and QMP PHYs) support
runtime PM to reduce PHY power consumption during bus_suspend.
Add changes to let core auto-suspend PHYs on host bus-suspend
using GUSB2PHYCFG register if needed for a platform. Also perform
PHYs runtime suspend/resume and let platform glue drivers e.g.
dwc3-qcom handle remote wakeup during bus suspend by waking up
devices on receiving wakeup event from PHY.
