power-utils: Initially use i2c in updater

Create I2CDevice in updater and invoke read() in doUpdate(), that could
be used in future.
Use mocked I2CInterface in updater's unit test case.

Tested: Manually verify on Witherspoon that the i2c device is opened
        and closed during PSU code update.
