This patch enables USB Test Mode control
from a new "testmode" file in sysfs:
   - write "-1" to this file to get some help
   - write another value to select a test mode
   - read this file to get current TM register value

This control can be used in USB Host or Device mode.
This will be very useful in case of host mode.

Tabify all the declarations here!

   To me, they already look tabified. What do you mean?
