Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20181016-1' into staging

target-arm queue:
 * hw/arm/virt: add DT property /secure-chosen/stdout-path indicating secure UART
 * target/arm: Fix aarch64_sve_change_el wrt EL0
 * target/arm: Define fields of ISAR registers
 * target/arm: Align cortex-r5 id_isar0
 * target/arm: Fix cortex-a7 id_isar0
 * net/cadence_gem: Fix various bugs, add support for new
   features that will be used by the Xilinx Versal board
 * target-arm: powerctl: Enable HVC when starting CPUs to EL2
 * target/arm: Add the Cortex-A72
 * target/arm: Mark PMINTENCLR and PMINTENCLR_EL1 accesses as possibly doing IO
 * target/arm: Mask PMOVSR writes based on supported counters
 * target/arm: Initialize ARMMMUFaultInfo in v7m_stack_read/write
 * coccinelle: new inplace-byteswaps.cocci to remove inplace-byteswapping calls
