Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20180518' into staging

target-arm queue:
 * Initial part of SVE implementation (currently disabled)
 * smmuv3: fix some minor Coverity issues
 * add model of Xilinx ZynqMP generic DMA controller
 * expose (most) Arm coprocessor/system registers to
   gdb via QEMU's gdbstub, for reads only
