[PATCH] USB Storage: add support for Maxtor One-Touch button

This patch is originally from Nick Sillik, and has been rediffed against
the latest tree.

This patch adds usability to the OneTouch Button on Maxtor External USB
Hard Drives. Using an unusual device entry it declares an extra init
function which claims the interrupt endpoint associated with this
button.  The button is connected to the input system.
