platform/x86: dell-ddv: Prefer asynchronous probing
During probe, both sensor buffers need to be queried to
initialize the hwmon channels. This might be slow on some
machines, causing a unnecessary delay during boot.
Mark the driver with PROBE_PREFER_ASYNCHRONOUS so that it
can be probed asynchronously.
