[PATCH] virtio: make VIRTIO a menuconfig to ease disabling it all

[Vincent Legoll]

No need to get into the submenu to disable all VIRTIO-related
config entries.

This makes it easier to disable all VIRTIO config options
without entering the submenu. It will also enable one
to see that en/dis-abled state from the outside menu.

This is only intended to change menuconfig UI, not change
the config dependencies.

v2: Added "default y" to avoid breaking existing configs
v3: Fixed wrong indentation, added *-by from Randy
