libdrm does not like the empty string for driver date. Use "0" instead,
which has been used by virtio previously.
Reported-by: Steven Price <steven.price@arm.com>
Closes: https://lore.kernel.org/r/9d0cff47-308e-4b11-a9f3-4157dc26b6fa@arm.com
Fixes: 7fb8af6798e8 ("drm: deprecate driver date")

It's a pity that libdrm can't cope with the empty string, using 0 makes sense.
