Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20200130' into staging

target-arm queue:
 * hw/core/or-irq: Fix incorrect assert forbidding num-lines == MAX_OR_LINES
 * target/arm/arm-semi: Don't let the guest close stdin/stdout/stderr
 * aspeed: some minor bugfixes
 * aspeed: add eMMC controller model for AST2600 SoC
 * hw/arm/raspi: Remove obsolete use of -smp to set the soc 'enabled-cpus'
 * New 3-phase reset API for device models
 * hw/intc/arm_gicv3_kvm: Stop wrongly programming GICR_PENDBASER.PTZ bit
 * Arm KVM: stop/restart the guest counter when the VM is stopped and started
