usb: patches for v3.17 merge window

Browse source 
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.
