"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
