Flush icache after dma operations for ia64
ia64 system depends on that platform issues snoop cycle to flush
icache for memory touched by DMA write operations, but virtual DMA
operations is emulated by memcpy, so use explict instrustions to flush
the related icache, otherwise, guest may use obsolete icache.
