To support flattened dwc3 dt model and drop the glue layer, introduce the
`dwc3-generic` driver. This enables direct binding of the DWC3 core driver
and offers an alternative to the existing glue driver `dwc3-of-simple`.

You're still not using the new pm_ptr()/pm_sleep_ptr. The kernel build
bot will complain about the maybe unused functions.

Thanks for your patience.
I found they are caused by using SET_RUNTIME_PM_OPS and SET_SYSTEM_SLEEP_PM_OPS macros.
I'll replace them with new RUNTIME_PM_OPS/SYSTEM_SLEEP_PM_OPS and wrap the
dwc3_generic_dev_pm_ops with pm_ptr()
