usb: gadget: patches for v3.8 

renesas_usbhs implements ->pullup() method, switches over
 to devm_request_irq(), adds support for DMA Engine and
 got a few miscelaneous cleanups.
 
 The NCM gadget got an endianness fix and the Ethernet
 gadget a frame size fix.
 
 We're finally removing the g_file_storage gadget and
 sticking to g_mass_storage and the new tcm_usb_gadget
 gadgets since that was a huge duplicaton of effort anyway.
 
 While removing g_file_storage, we also had to fix a bunch
 of defconfigs which were still pointing to the old gadget.
 
 There's a big series getting us closer to being able to
 introduce our configfs interface. The series converts
 functions into loadable modules which will, eventually,
 be registered to the configfs interface.
 
 Other than that there's the usual typo fixes and miscelaneous
 cleanups all over the place.

The Mass Storage Function and thus the Mass Storage Gadget has been
based on the File Storage Gadget. The difference between the two is
that MSG is a composite gadget (ie. uses the composite framework)
while file storage gadget is a traditional gadget. From userspace
while file storage gadget was a traditional gadget. From userspace
point of view this distinction does not really matter, but from
kernel hacker's point of view, this means that (i) MSG does not
duplicate code needed for handling basic USB protocol commands and
(ii) MSF can be used in any other composite gadget.
Because of that, File Storage Gadget has been deprecated and
scheduled to be removed in Linux 3.8. All users need to transition
