Mass storage spec allows up to 16 LUNs, so let's not
add some more restrictive limits.

Creation of LUN 0 may fail (for example due to ENOMEM).
As fsg_common_set_num_buffers() does some memory allocation
we should free it before it becomes unavailable.

Mass storage function created via configfs always reports eight LUNs
to the hosts even if only one LUN has been configured. Adjust the
number when the USB function is allocated based on LUNs that user
has created.

As usual, a big pile of commits. This time a total
of 111 non-merge commits.
Other than the usual set of cleanups and non-critical
fixes, we have some interesting work for AM335x's MUSB
babble recovery. Now that takes a lot less time and we
don't have to Reset MUSB all the time.
The printer gadget has been converted to configfs interface
and the atmel udc has learned suspend/resume with wakeup.

Instead of manual device_create_file() and device_remove_file() calls,
assign the static attribute groups to the lun device to register.
The RO or RW permissions for some entries are decided in is_visible
callback. This simplifies the code (also the logic) and avoids the
possible races, too.

Flatten the start_transfer function by reversing the if condition and
returning early out of the function if everything went fine. It makes
the function look less complicated, at least to me, and easier to
understand.

This patch moves the USB functions implementations into a separate directory.
