    docs: allow generic virtio device types to contain device-id
    
    For generic virtio devices, where we don't need to add compatible or
    other special DT properties, the type field is set to "virtio,device".
    
    But this misses the case where the user sets the type with a valid
    virtio device id as well, like "virtio,device1a" for file system device.
    The complete list of virtio device ids is mentioned here:
    
    
https://docs.oasis-open.org/virtio/virtio/v1.2/cs01/virtio-v1.2-cs01.html#x1-2160005
    
    Update documentation to support that as well.
    
    Fixes: dd54ea500be8 ("docs: add documentation for generic virtio devices")
