usb: dwc3: Add Qualcomm DWC3 glue driver
DWC3 controller on Qualcomm SOCs has a Qscratch wrapper.
Some of its uses are described below resulting in need to
have a separate glue driver instead of using dwc3-of-simple:
- It exposes register interface to override vbus-override
and lane0-pwr-present signals going to hardware. These
must be updated in peripheral mode for DWC3 if vbus lines
are not connected to hardware block. Otherwise RX termination
in SS mode or DP pull-up is not applied by device controller.
- pwr_events_irq_stat support to check if USB2 PHY is in L2 state
before glue driver proceeds with suspend.
- Support for wakeup interrupts lines that are asserted whenever
there is any wakeup event on USB3 or USB2 bus.
- Support to replace pip3 clock going to DWC3 with utmi clock
for hardware configuration where SSPHY is not used with DWC3.
