Changes to fix bad DMA handling by disk when using scatter gather page
mappings (writes still unverified, and read could probably be looked over
a bit more too)
dev/ide_disk.cc:
dev/ide_disk.hh:
Major changes to fix bogus handling of dma transfers. The read seems to
work pretty well, but the write is unverfied until we can get a disk
image that actually tries to write.
dev/tsunami_pchip.cc:
Change mask to properly mask 13 bits not 12
