This patch introduces support for test modes as
defined by the USB OTG & Embedded host Specification.

Note that we _must_ be able to suspend & resume ports
as we wish, so this driver depends on USB_SUSPEND and
makes use (well, somewhat abuses) usb autopm features
to achieve what we want.

Fixes issue reported in ticket #52637

Using UBI on m25p80 can give messages like:

    UBI error: io_init: bad write buffer size 0 for 1 min. I/O unit

We need to initialize writebufsize; I think "page_size" is the correct
"bufsize", although I'm not sure. Comments?

Multiple assignments should not occur and will cause a hang if they do.
