sgi-xp: eliminate '>>>' in comments

Comments in /drivers/misc/sgi-xp has been using '>>>' as a means to draw
attention to something that needs to be done or considered.  To avoid
colliding with git rejects, '>>>' will now be replaced by '!!!' to
indicate something to do, and by '???' to indicate something to be
considered.
