Three lines with more than 80 characters per line have been split in several lines.

As for the comment-line changes... 80+ chars are allowed for better readability.
So, please don't do that.
[ Checkpatch should not warn on this especially for comments. ]

We almost always split long comments into separated lines in the
kernel. What's different with this case?

1st it is not mandatory.

2nd it is more readable in one line.

-                       /* 4706 CC and PMU watchdogs are clocked at
1/4 of ALP clock */
+                       /* 4706 CC and PMU watchdogs are clocked at 1/4 of ALP
+                        * clock
+                        */

I agree with you when the comment would be longer.

So I guess there is some rule like
"Don't use 2 lines if there is 80 chars + one word"
? Where can I find such rules?

Personally, I don't like taking this sliding slope. Just stick to the 80 
characters rule and add a few words in the comment, eg:

			/* The BCM4706 ChipCommon and PMU watchdogs are
			 * clocked at one quarter of the ALP clock.
			 */
