Rename _bus_dma_can_bounce(), add new inline routines.

DMA on arm can bounce for several reasons, and _bus_dma_can_bounce() only
checks for the lowaddr/highaddr exclusion ranges in the dma tag, so now
it's named exclusion_bounce().  The other reasons for bouncing are checked
by the new functions alignment_bounce() and cacheline_bounce().
