Rename battery pack file and limit trickle charging current
The spec of link internal battery pack changed. This CL adds
parameter for new pack, and renames vendor specific source file
accordingly.
The new trickle charging current limit should fix the slow
pre-charging issue.

BUG=chrome-os-partner:11298,10201
TEST=manual
The minimum trickle charging current should be very close to
0.01 C (85mA). Previous battery pack firmware uses 5mA in pre-
charging.
