Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20160714' into staging

target-arm queue:
 * add virtio-mmio transport base address to device path
   (avoid an assertion failure with multiple virtio-scsi-devices)
 * revert hw/ptimer commit 5a50307b which causes regressions on
   SPARC guests
 * use Neon to accelerate zero-page checking on AArch64 hosts
 * set the MPIDR for TCG to match how KVM does it (and fit with
   GICv2/GICv3 restrictions on SGI target lists)
 * add some missing AArch32 TLBI hypervisor TLB operations
 * m25p80: Fix QIOR/DIOR handling for Winbond
 * hw/misc: fix typo in Aspeed SCU hw-strap2 property name
 * ast2400: pretend DMAs are done for U-boot
 * ast2400: some minor code cleanups
