powerpc: Add a shutdown member to vio_driver
Add a shutdown member to struct vio_driver. We also need vio_bus_shutdown() which converts from struct device to struct vio_dev and knows how to extract the struct vio_driver. Original patch adjusted for different location of vio.c. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
