[PATCH] I2C: Improve core debugging messages

The debugging messages in i2c-core are more confusing than helpful. Some
lack their trailing newline, some lack a prefix, some are redundant,
some lack precious information. Here is my attempt to introduce some
standardization in there.

I also changed two messages in i2c-dev to make it clear they come from
i2c-dev.
