ec/google: Support Google's Chrome EC on I2C interface.

Google's Chrome EC can be installed on LPC or I2C bus, using different command
    protocol.  This commit adds I2C support for devices like Google/Snow.

Note: I2C interface cannot be automatically probed so the bus and chip number
    must be explicitly set.

Verified by booting Google/Snow, with following console output:
      Google Chrome EC: Hello got back 11223344 status (0)
      Google Chrome EC: version:
         ro: snow_v1.3.108-30f8374
         rw: snow_v1.3.128-e35f60e
        running image: 1
