usb: patches for v3.17 merge window

Surprisingly enough, while a big set of patches, the majority is
composed of cleanups (using devm_*, fixing sparse errors, moving
code around, adding const, etc).

The highlights are addition of new support for PLX USB338x devices,
and support for USB 2.0-only configurations of the DWC3 IP core.
