Another intermediate version of sba_iommu.c.
my c3000 HPMC's when tulip driver enables TX for the first packet.
Confirmed (via PCI bus trace) tulip chip generates a valid mem read to
host mem aquired via alloc_consistent() interface.
Something is still wrong with IOC/Elroy initialization.

o PDIR_INDEX fixed.
o got rid of loops for generating bit masks.
o fixed ibase initialization.
o fixed bugs in pdir programming (and it now looks right)
