The code in this block is unused and the Author is fine with removing:
| These functions were used to debug unstable hw fifo while developing
| fusb300. It's much more stable now.
| So these functions can be removed.

- remove pointer u32 abuse in fusb300_fill_idma_prdtbl().
It is assigned the dma_addr to a pointer and then back.
Poor families may have to recycle variables but we don't
- don't free req.buf in error case. We don't do it in the
ok case so it is probably wrong to do it in error case.
- return in error case. There is no reason to continue
without data and performing ops on an invalid pointer.
- The if (d) statement is bogus since an invalid DMA pointer
is ~0 on some architecutres. And since we return for the
invalid case we don't need it.

that code has been dead forever. Since the
first commit (0fe6f1d1) the use of that code
has been commented out. Let's drop the dead
code already and fix the following compile

peripheral drivers are using usb_add_gadget()/usb_del_gadget() to
register/unregister to the udc-core.
The udc-core will take the first available gadget driver and attach
function driver which is calling usb_gadget_register_driver(). This is
the same behaviour we have right now.
Only dummy_hcd was tested, the others were compiled tested.
