restart_dma is not used before it is declaration. Therefore we can
remove this definition.

use_dma parameter was designed to enable the dma on the chip. It was
enabled by default.
It comes from the time when the dma was not reliable. Now it has been
working ok in production.
This patch removes this parameter.

Parameter use_msi was used to enable msi irq on usb338x chips, it was
enabled by default.
There is no reason to prefer non-msi irq on usb338x, and it falls back
to non msi on error.
Therefore remove this option.

This patch removes the full_speed parameter used force full-speed
operation.
It was designed exclusively for testing purposes, and there is no
reason to maintain this in a production kernel.

use_dma_chaining module parameter was designed to avoid creating one irq
per package on a group of packages (with the help of the driver's flag
no_interrupt).
Unfortunately, when this parameter is enabled, the driver fails to work
on both net2280 and 3380 chips.
This patch removes this parameter, which was disabled by default.

Parameter three in function call dma_done() is incorrect.
Move use of variable 'tmp' after if-condition.

now that no UDC driver relies on the extra
'driver' argument to ->udc_stop(), we can
safely remove it.
This commit is based on previous work by
Robert Baldyga <r.baldyga@samsung.com> which
can be found at [1]; however that patch turned
out to have a high probability of regressing
many UDC drivers because of a blind search & replace
s/driver/$udc->driver/ which caused the 'driver'
argument to stop_activity() to be a valid non-NULL
pointer when it should be NULL, thus causing UDCs
to mistakenly call gadget driver's ->disconnect()
callback.

now that we provide generic register/unregister
debugging messages from udc-core, we can remove
the same messages from this driver.

future patches will remove the extra 'driver'
argument to ->udc_stop(), in order to do that,
we must make sure that our UDC does not rely
on it first.

Use the recently introduced usb_gadget_giveback_request() in favor of
direct invocation of the completion routine.
All places in drivers/usb/ matching "[-.]complete(" were replaced with a
call to usb_gadget_giveback_request(). This was compile-tested with all
ARM drivers enabled and runtime-tested for musb.

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