Log Message:
tweak x86 bus_dma code so that it can be used by xen port.

- distinguish paddr_t and bus_addr_t.
  for xen, use bus_addr_t in the sense of machine address.
- move _X86_BUS_DMA_PRIVATE part of bus.h into bus_private.h.
- remove special handling of xen_shm.  we can always grab
  machine address from pte.
