This patch allows the gadget portion of the DWC2 driver to get built when
(!USB && USB_GADGET) condition is encountered.

Moves the s3c-hsotg driver into the dwc2 directory and uses the
dwc2 defines in hw.h. Renames s3c-hsotg.c to gadget.c.
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
soon.

[ pz: Folded Kconfig/Makefile changes, which were originally in
a separate patch, into this one, to avoid a build breakage.
Modified Kconfig/Makefile changes a bit. Tested host part only. ]

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.
