Remove the x86 and i386 prefixes to the bus_dma types. It's really quite

pointless and just makes the code different for no reason. This moves i386 and
amd64 bus_dma to being a lot closer to identical.

suggestion to just remove the prefix instead of merge them from deraadt@.

no objections art@, kettenis@, ok weingart@
