Add BQ27541 battery driver
BQ27541 is not a smart battery IC, and thus we cannot use existing smart
battery driver. Let's add a driver that implements a smart-battery-like
interface.
The 'battery' console command is also moved to battery.c so that it can
be reused by different battery driver.
BUG=chrome-os-partner:22048
TEST=Type 'battery' and check the reported values are sane.
TEST=Check 'battery' command works fine on Spring.
BRANCH=None
