usb: gadget: Add the console support for usb-to-serial port

It dose not work when we want to use the usb-to-serial port based
on one usb gadget as a console. Thus this patch adds the console
initialization to support this request.

To avoid the re-entrance when transferring data with usb endpoint,
it introduces a kthread to do the IO transmission.

The old function interface is provided by means of preprocessor conditional
directives. After all users are converted, the old interface can be
removed.

This patch adds support for the PLX USB3380 and USB3382.

This driver is based on the driver from the manufacturer.

Since USB338X is register compatible with NET2280, I thought that it
would be better to include this hardware into net2280 driver.

Manufacturer's driver only supported the USB33X, did not follow the
Kernel Style and contain some trivial errors. This patch has tried to
address this issues.

been done trying to not affect the behaviour of NET2280.

NOTE: You can build both host and peripheral as a dynamically
linked module, but be aware that if you insmod dwc2_gadget, then
rmmod it, then insmod dwc2 and dwc2_platform for host mode, this
will not work. As the step to rmmod dwc2_gadget.ko will turn off
the clock to the USB IP. The dwc2 host driver currently does not
look to turn on a clock yet. A patch to fix that will be coming
