i2c-pxa: only define 'blue_murder'-function if DEBUG is #defined
This talkative function is also called on timeouts. As timeouts can happen on regular writes to EEPROMs (no error case), this creates false positives. Giving lots of details is interesting only for developers anyhow, so just use the function if DEBUG is #defined.
