mb/google/hatch: Add smart battery I2C passthrough for Dratini
Some smart battery patches have been backported to the ChromeOS 4.19 kernel,
and userspace can now access smart battery data from sysfs instead of using
the hacky ectool instead.
Also change all space indents into tab indents while we're here.
BUG=chromium:1047277
TEST=confirmed a /sys/class/power_supply/sbs-i2c device shows up
