[PATCHv6 0/8] usb: dwc2: Add support for dual-role

[<dinguyen@opensource.altera.com>]

From: Dinh Nguyen <dinguyen@opensource.altera.com>

Hello,

This is version 6 of the patch series that combines the dwc2 gadget and host
driver into a single dual role driver. Here are the main differences from V5:

- Added a new patch 8/8 - usb: dwc2: move usb_disabled() call to host driver
  only. This patch is needed to avoid a build error when (!USB && USB_GADGET)
  condition is met.
- Addressed comments in the Kconfig/Makefile. USB_DWC2_PLATFORM and
  USB_DWC2_PCI are now tristate.

For v6, the series is rebased on top of Felipe Balbi's tree on testing/next
branch. I thought this might be appropriate as there are dwc2 patches already
on this branch.

As usual, tested on SOCFPGA(host, gadget, and dual-role) and on Rpi-B
(host mode only).

I have pushed this series to a git repo to make it more convenient for people
to test/review.
