I think that the alternate function stuff is right (I say this with
the caveat that I haven't yet used NSSP). This allows it to act either
as a master or a slave (you'll notice that what changes is just the
direction on the pins).
If the docs are right GP83/84 are interesting in that either one can
Tx or Rx and you'd just need to configure things properly.
I don't believe that any kernel drivers are currently using NSSP and
all of the pins seem to be available on the Waysmall and breakout
