virtio: console as a config option
I also added a small Kconfig change that allows the user to specify the virtio console in menuconfig. (Fixes to export symbols from Stephen Rothwell <sfr@canb.auug.org.au>) (Fixes for CONFIG_VIRTIO_CONSOLE=y vs CONFIG_VIRTIO=m from Christian himself) Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Cc: Stephen Rothwell <sfr@canb.auug.org.au>
