VS4000 TURBOchannel support added

[Felix Deichmann <flxd%NetBSD.org@localhost>]

Hi,

I committed VAXstation 4000 TURBOchannel support to current (not in
netbsd-8 yet), and it would be great if it make it into -8 before NetBSD
8.0 gets released...

PIO and IRQ tested on VS4000/60 and /96 with TC-USB (slhci) and PMAD-AA
(le).
DMA is untested, and will probably only work in VS4000/{90, 90A, 96}.
vax needs space to be mapped out, so memory space is pre-mapped for TC
option drivers not bus_space'ified yet, also providing custom bus_space
methods for this kludge.

Please test if you have the hardware, especially DMA, as I still did not
manage to get a TC DMA option. Anyone?

For large kernels e.g. with full USB support :), you'll also need a
modified 2nd stage boot loader (RELOC=0x3f0000 not enough). I can help
out with binaries for all that.

Felix
