This reverts commit8f8c04bf1e. The commit is largely wrong and breaks most of i2c command functionality. The problem described in the aforementioned commit commit message is valid, however the commit itself does many more changes unrelated to fixing that one problem it describes. Those extra changes, namely the handling of i2c device address length as unsigned instead of signed integer, breaks the expectation that address length may be negative value. The negative value is used by DM to indicate that address length of device does not change. The actual bug documented in commit8f8c04bf1ecan be fixed by extra sanitization in separate patch.
