8390: Split 8390 support into a pausing and a non pausing driver core
Only a few ISA controllers need the pausing version of the 8390 core
while PCMCIA, later ISA and PCI do not. More importantly the ISA delays
can break non ISA boxes so we must use a different build of 8390.c for
the two sets of controllers.
No changes since last time as all the points of concerns raised proved to
be invalid
