That comment was written prior to knowing that what I was actually
seeing was a manifestation of the bug fixed in commit b4024c9e
("felix: Fix initialization of ioremap resources").

There isn't any particular reason now why the hardware initialization is
done in felix_setup(), so just delete that comment to avoid spreading
misinformation.
