[RFC: 2.6 patch] remove the USB_STORAGE_ONETOUCH driver

[Adrian Bunk <bunk@kernel.org>]

Nearly two years ago, USB_STORAGE_ONETOUCH got a dependency on !PM.
Considering that this also implies that the driver is not available
e.g. when ACPI is enabled in the kernel that's not far from a dependency 
on BROKEN.

This patch therefore removes this driver.
