i2c: Clean up <linux/i2c.h>
Fix most checkpatch.pl errors and warnings. This includes replacing spaces with tabs in many places, adding and removing spaces, and folding long lines. Also complete a couple prototypes to make it clearer what the parameters represent. Signed-off-by: Jean Delvare <khali@linux-fr.org>
