[PATCH] mips: DECstation Turbochannel updates 

Update Turbochannel code.  Right now the code is basically still at the state
of 2.3; with this patch applied it'll roughly on the level of the TC code in
early 2.4 with a bunch of 2.6 fixes on top.  Not great but will bring the code
closer into touch with reality until Maciej has a chance to finally tackle
things.
