Add support for the Cypress CY82C693 PCI-ISA bridge. This bridge is more or

less like an Intel SIO except that the ELCR registers are accessed differently
than on the Intel SIO.
XXX This code needs to be split up into bridge front-end and PIC back-end
XXX pieces.

A little buglet: softc for pceb is same as sio- so declare it as such.
...
By not doing so, a very obscure bug followed where the config search
stuff stopped at the bridge (pceb) and didn't even call match for the
two Qlogic ISP cards that followed.

Remove references to pmap.old.h - It should have just been pmap.h, but

Redo it slightly so that S/G now appears to work a bit better. This

version has 2GB direct map starting at 2GB, and either 256MB or 1GB
S/G starting at 1MB. I've done *some* testing on this, but I'm not
quite happy with it yet.

Do a more complete job of figuring out what kind of DWLP? we have- figure
...
out how much s/g ram is available. Can't really use the 128K entry S/G
ram yet- but I'll fix that later. More importantly, add in a dwlpx_iointr
handler that will try and figure out what the DWLPX error is and at
least print out what is happening- I actually found it useful in S/G
entry debugging as it could tell me that I had some bad S/G entries.

Add a "scrollskip" member to wscons_emulfuncs (XXX even though it's not
...
a function) which specifies how many lines will be skipped when scrolling
up when the bottom of the screen is reached. Dumb framebuffers skip 10
lines (as before) because the copies are s ... l ... o ... w, but it's
silly to skip 10 lines on VGA, since the copies are much faster, so we
only skip one in that case.
