USB: remove the berry_charge driver 

The Barry project's userspace program, bcharge, can better handle this
device and functionality, and it also works with the latest phones,
which this driver does not support.  So remove it, as the userspace code
should be used instead.

Say Y here if you want to connect a BlackBerry device to your
computer's USB port and have it automatically switch to "recharge"
mode.
