Rework PCI interrupt mapping on the EB164 systype. Rather than computing
...
interrupt routing directly, use the interrupt routing information provided
in the PCI "line" register. The previous scheme did not work properly on
AlphaPC 164SXs. Also, be silent about the fact that 0/8/x does not
have its interrupt mapped; this is to be expected on the 164SX (this is
the Cypress PCI-ISA bridge, which has IDE wired to compat mode on functions
1 and 2; the 164SX does _not_ have PCI IDE on device 11 like other AlphaPCs).

Simplify the direct-mapped DMA case somewhat by adding a window base

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

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.
