The i.MX USB glue and DWC3 core are closely coupled. Describe the i.MX
USB block in a single block will bring more benefits than a parent-
child relation.

Now DWC3 USB common driver already support to do more key jobs in glue
driver, such as power management and core initialization. Now let's
make a step and add a flatten devicetree based driver.

The first one add a new "nxp,imx-dwc3.yaml" binding to describe all i.MX
related USB controller.

Then, to support wakeup capability even when controller experienced
power lost, a fix patch is added to make controller work after system
resume back.
