hw/vmapple/virtio-blk: Add support for apple virtio-blk
Apple has its own virtio-blk PCI device ID where it deviates from the official virtio-pci spec slightly: It puts a new "apple type" field at a static offset in config space and introduces a new barrier command. This patch first creates a mechanism for virtio-blk downstream classes to handle unknown commands. It then creates such a downstream class and a new vmapple-virtio-blk-pci class which support the additional apple type config identifier as well as the barrier command. The 'aux' or 'root' device type are selected using the 'variant' property.
