Log Message:
Checkpoint of code to add VMEbus slave support using vme_dmamap* and
vme_dmamem*.

This is still a work in progress, but seems to DTRT on mvme167 so far.

TODO:
	. Get VMEbus slave mode going on mvme147. This should be easy.
	. Fix up the A16 slave mappings.
	. Bounce buffer support. (Messy, but pretty much a `must have'.)
	. Figure out how to deal with `location monitor' interrupts
	  within the framework. (Useful for Busnet, among other things.)
	. It would be nice to make use of the VMEchip2's DMA facilities...
