sysbus: add MemoryRegion based memory management API
Allow registering sysbus device memory using a MemoryRegion. Once all users are converted, sysbus_init_mmio() and sysbus_init_mmio_cb() will be removed. Reviewed-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
