Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20180626' into staging

Browse Source 
target-arm queue:
 * aspeed: set APB clocks correctly (fixes slowdown on palmetto)
 * smmuv3: cache config data and TLB entries
 * v7m/v8m: support read/write from MPU regions smaller than 1K
 * various: clean up logging/debug messages
 * xilinx_spips: Make dma transactions as per dma_burst_size
