virtio-pstore: Support PSTORE_TYPE_CONSOLE
With help of buffer management functions, it now supports CONSOLE type
pstore write. The config space has flags field which defines the
VIRTIO_PSTORE_CONFIG_FL_CONSOLE. When it's set, the virtio-pstore
driver also sets PSTORE_FLAGS_ASYNC so that the buffer management is
enabled.
