Add blank line between paragraphs or wrap into a single paragraph.

Add space before open paren, e.g., "ICC (interconnect consumers)",
"NoC (Network on Chip)".

"... remove the disable this path ..." has too many verbs :)
Maybe "When suspending, disable this path ..."?

Wrap to fit in 80 columns.

One of the other patches has s/cpu/CPU/ in it.  Please do the same
here.
