Annotate pc300 wan driver PCI memory accesses. 

This driver caused a _lot_ of warnings due to tons
of explicit casts to "uclong". Making all the types
sane not only removed the warnings, but got rid of
a lot of silly casting, since the types are now much
more natural to what the driver wanted to do in the
first place.
