USB: Support Blackberry Pearl with berry_charge

Browse Source 
The Blackberry Pearl (8100) needs similar tweaks as older Blackberry models
to be able to charge when connected via USB.  The Pearl also adds an
additional need to go into a separate mode for fully accessing the device;
do that by default as well.

Changes based on the changes from bcharge in the barry project
(http://barry.sf.net)
