This moves battfake console command to the battery driver.
This fixes a race condition with using the 'battfake' command
where charge_state_v2 could return the real battery percentage
even when a faked percentage is specified, if a higher priority
task uses the battery state of charge in between when the
battery is read, and when the fake state of charge overwrites
the battery parameter.
BUG=chrome-os-partner:45878
BRANCH=none
TEST=use tap for battery with a faked state of charge. the tap
for battery queries the battery percentage a lot, so without
this CL, the tap sequence often temporarily jumps to different
percentages and colors. with this CL, the tap sequence works
great.
