This reverts commit ef11982dd7a657512c362242508bb4021e0d67b6.
That commit creates a problem for some UDCs (at least musb)
where it allocates an endpoints with a 64-byte FIFO, but later
tries to use that same FIFO for 1024-byte packets.
Before implementing this, composite framework needs to be
modified so we only allocate endpoints after we know negotiated
speed, however that needs quite a bit of extra work.

Interrupt endpoints behave quite similar to the bulk endpoints with the
difference that the endpoints expect data sending/reception request at
particular intervals till the whole data has not been transmitted.
The interrupt EP support is added to gadget zero. A new alternate setting (=2)
has been added. It has 2 interrupt endpoints. The default parameters are set as:
bInterval: 1 ms for FS and 8 uFrames (implying 1 ms) for HS/SS
wMaxPacketSize: 64 bytes for FS and 1024 bytes for HS/SS
However, the same can be overridden through the module parameter interface.
The code is tested for HS and SS on a platform having DWC3 controller.

The drivers/usb/gadget directory contains many files.
Files which are related can be distributed into separate directories.
This patch moves the USB functions implementations into a separate directory.
