2.2.2.1. I2C test
For verifying the I2C bus, a full I2C bus scanning will be performed
-using the i2c_probe() routine. If any I2C device is found, the test
-will be considered as passed, otherwise failed. This particular way
-will be used because it provides the most common method of testing.
-For example, using the internal loopback mode of the CPM I2C
-controller for testing would not work on boards where the software
-I2C driver (also known as bit-banged driver) is used.

+CONFIG_SYS_POST_I2C_ADDRS the I2C test will pass if all devices
+listed in CONFIG_SYS_POST_I2C_ADDRS are found, and no additional
+devices are detected. If CONFIG_SYS_POST_I2C_ADDRS is not defined
