post/i2c: Don't probe address 0
According to the I2C specification device address 0 is the "general call
address", ie a broadcast address. The I2C specification states that the
format of a general call uses at least 2 bytes, which U-Boot's probing
routine does not adhere to.
Not probing device address 0 will prevent possible issues with devices
that accept general calls. Additionally, this change shouldn't reduce
POST coverage since each I2C device should still be accessed via its
own, unique address.
