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.

+
+          If you choose to build this driver as dynamically linked
+          modules, the core module will be called dwc2.ko, the
+          PCI bus interface module (if you have a PCI bus system)
+          will be called dwc2_pci.ko and the platform interface module
+          (for controllers directly connected to the CPU) will be called
+          dwc2_platform.ko.
+
+          NOTE: This driver at present only implements the Host mode
+          of the controller. The existing s3c-hsotg driver supports
+          Peripheral mode, but only for the Samsung S3C platforms.
+          There are plans to merge the s3c-hsotg driver with this
+          driver in the near future to create a dual-role driver.
