All USB peripheral controller drivers call completion routines directly.
This patch adds usb_gadget_giveback_request() which will be used instead

In the next commit, we will want the usb-common module to be composed of
two object files. Since Kbuild cannot append another object to an
existing one, we need to rename usb-common.c to something
else (common.c) and create usb-common.o by linking the wanted objects
together. Currently,

With this patch, USB activity can be signaled by blinking a LED. There

Both triggers should work with all host/device controllers. Tested only

ARM drivers enabled and runtime-tested

For this preparation, a preliminary cleanup is done :
- convert the probing of pxa27x_udc to gpio_desc.
The conversion is partial because :
- the platform data still provides a gpio number, not a gpio desc
