c2c02249a0 host: mock i2c_xfer
Instead of mocking i2c_read8/16/32, mock i2c_xfer.
We can now test code that call i2c_xfer directly and
test common/i2c.c

BRANCH=samus, ryu
BUG=chrome-os-partner:45223
TEST=Unit tests pass.

4de56d4a7f Test interface for detaching fake I2C devices
This provides an interface to detach and re-attach fake I2C devices,
which can be used to test I2C connection failure.

d5e183f9e5 Fake I2C device support for emulator
To test drivers, we need a way to fake I2C periphrals. With this CL, a
fake peripheral can be done by declaring its own I2C read/write
functions. The fake I2C peripherals may return EC_ERROR_INVAL to
indicate it's not responding. The emulator I2C read/write call scans
through all registered I2C peripherals and uses the first response.

TEST=Pass sbs_charging test with the next CL.

93cb494a7e 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
