Konstantin Belousov 3f9d41ed10 Add a virtual table for the busdma methods on x86, to allow different
busdma implementations to coexist.  Copy busdma_machdep.c to
busdma_bounce.c, which is still a single implementation of the busdma
interface on x86 for now.  The busdma_machdep.c only contains common
and dispatch code.
