Move DWC2 driver out of staging

The DWC2 driver should now be in good enough shape to move out of
staging. I have stress tested it overnight on RPI running mass
storage and Ethernet transfers in parallel, and for several days
on our proprietary PCI-based platform.

-TODO:
-        - Dan Carpenter would like to see some cleanups to the microframe
-          scheduler code:
-          http://www.mail-archive.com/linux-usb@vger.kernel.org/msg26650.html
-
-        - Should merge the NAK holdoff patch from Raspberry Pi
-          (http://marc.info/?l=linux-usb&m=137625067103833). But as it stands
-          that patch is incomplete, it needs more investigation to see if it
-          can be made to work for non-Raspberry Pi platforms that lack the
-          special FIQ interrupt that the Pi has. Without this patch, the driver
-          has a high interrupt rate (8K/sec).
-
-        - The Raspberry Pi platform needs to have support for its FIQ interrupt
-          added, to get the same level of functionality as the downstream
-          driver. The raspberrypi.org developers have indicated they are
-          willing to help with that.
-
-        - Some of the default driver parameters (see 'struct dwc2_core_params'
-          in core.h) won't work for many platforms. So DT attributes will need
-          to be added for some of these. But that can be done as-needed as new
-          platforms are added.
-
-        - Eventually the driver should be merged with the s3c-hsotg peripheral
-          mode driver, so that both modes of operation can be supported with a
-          single driver. But I think that can wait till after the driver has
-          been moved to mainline.
-
-        - After that, OTG support can be added. I'm not sure how much demand
-          there is for that, though, so I have that as a low priority.
-
-Please send any patches for this driver to Paul Zimmerman <paulz@synopsys.com>
-and Greg Kroah-Hartman <gregkh@linuxfoundation.org>. And please CC linux-usb
-<linux-usb@vger.kernel.org> too.
