Merge bus_dma support from NetBSD, mostly by Jason Thorpe. Only i386 uses it
so far, the other archs gets placeholders for now. I wrote a compatibility
layer for OpenBSD's old isadma code so we can still use our old
driver sources. They will however get changed to native bus_dma use,
on a case by case basis. Oh yes, I almost forgot, I kept our notion
of isadma being a device so DMA-less ISA-busses still work
