We have the PL022 as well, and the PL08x is being added but it will
likely stay in that ballpark figure.

But overall that does not seem to be worth it, so let's drop it
for the time being. CC:ing the linux-embedded folks that
often worry about footprint size to see if someone oppose. Also
CC Viresh who works on a platform for e.g. set-top boxes using
these PrimeCells which I think may be memory-constrained.
