usb: dwc2: Update Kconfig to support dual-role

	  Say Y here if your system has a Dual Role Hi-Speed USB

	  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. For gadget mode, there will be a single

	  module called dwc2_gadget.ko.

	  NOTE: The s3c-hsotg driver is now renamed to dwc2_gadget. The

	  host and gadget drivers are still currently separate drivers.

	  There are plans to merge the dwc2_gadget driver with the dwc2

	  host driver in the near future to create a dual-role driver.

	  dwc2_platform.ko. For all modes(host, gadget and dual-role), there

	  will be an additional module named dwc2.ko.
