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. Cc: Chris Frey <cdfrey@foursquare.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
