  Log:
  Sync bounce pages support with the alpha backend.  More precisely:
          o use a mutex to protect the bounce pages structure.
          o use a SYSINIT function to initialize the bounce pages structures
            and thus avoid a race condition in alloc_bounce_pages().
          o add support for the BUS_DMA_NOWAIT flag in bus_dmamap_load().
          o remove obsolete splhigh()/splx() calls.
          o remove printf() about incorrect locking in busdma_swi() and sync
            busdma_swi() with the one of the alpha backend.
          o use __FBSDID.
