[PATCHv5 0/7] usb: dwc2: Add support for dual-role

[<dinguyen@opensource.altera.com>]

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

Hello,

This is version 5 of the patch series that combines the dwc2 gadget and host
driver into a single dual role driver. Here are the main differences from V4:

- Squashed 5 patches from V4 into patch 2. Patchset is now only 7 patches.
- Makefile moved to be the last patch in the series.
- When building for kernel modules, dwc2.ko will get built for all modes(host,
  gadget, and dual-role). dwc2_platform.ko and dwc2_pci.ko will get built
  for platform SOC and PCI.

For v5, the series is rebased on top of v3.18-rc1.

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.
