usb: gadget: patches for v3.8

Browse source 
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.
