Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20190816' into staging

target-arm queue:
 * target/arm: generate a custom MIDR for -cpu max
 * hw/misc/zynq_slcr: refactor to use standard register definition
 * Set ENET_BD_BDU in I.MX FEC controller
 * target/arm: Fix routing of singlestep exceptions
 * refactor a32/t32 decoder handling of PC
 * minor optimisations/cleanups of some a32/t32 codegen
 * target/arm/cpu64: Ensure kvm really supports aarch64=off
 * target/arm/cpu: Ensure we can use the pmu with kvm
 * target/arm: Minor cleanups preparatory to KVM SVE support
