Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20180215-1' into staging

target-arm queue:
 * aspeed: code cleanup to use unimplemented_device
 * preparatory work for 'raspi3' RaspberryPi 3 machine model
 * more SVE prep work
 * v8M: add minor missing registers
 * v7M: fix bug where we weren't migrating v7m.other_sp
 * v7M: fix bugs in handling of interrupt registers for
   external interrupts beyond 32
