virtio IDs are allocated through the virtio TC.


Reserving this spcific one as a generic VIRTIO_ID_VENDOR is now under
discussion on the virtio-comments mailing list:

https://lore.kernel.org/all/20261022091645-mutt-send-email-mst@kernel.org/

Please
- switch your driver to use that + qualcomm vendor id +
  validating the device through the DT
- do not merge this yet, before the virtio TC has reserved the
  device ID.
