Subject: [PATCH v2 1/4] i2c: i801: remove printout on handled timeouts

I2C and SMBus timeouts are not something the user needs to be informed
about on controller level. The client driver may know if that really is
a problem and give more detailed information to the user. The controller
should just pass this information upwards. Remove the printout and turn
the SMBus-specific termination message to debug.
