Log Message:
Pull up following revision(s) (requested by bouyer in ticket #695):
	sys/arch/x86/x86/bus_dma.c: revision 1.22
	sys/arch/x86/include/bus_private.h: revision 1.2
More adjustements to deal with Xen's physical <=> machine addresses mappings:
- Allow _bus_dmamem_alloc_range to be provided from external source:
  Use a _PRIVATE_BUS_DMAMEM_ALLOC_RANGE macro, defined to
  _bus_dmamem_alloc_range by default.
- avail_end is the end of the physical address range. Define a macro
 _BUS_AVAIL_END (defined by default to avail_end) and use it instead.
