Alec Berg bcb9428312 samus: enable PP3300_ACCEL_EN by default 
Keep accelerometer power enabled all the time. It consumes
very little power, we will need it to be on all the time for
tap for battery, and when it is off, it can cause problems
because the PP3300_EC rail leaks through the i2c pull-ups into
the accelerometer.

With this change, we should never see the bug in which i2c
bus 1 is getting a lot of errors on boot.

BUG=chrome-os-partner:29003
BRANCH=none
TEST=tested on multiple samus units. can talk to accel using
i2cxfer console command, and never saw any bus problems.
