Input: Drop unused assignments from pnp_device_id arrays

Input: Drop unused assignments from pnp_device_id arrays

Explicitly assigning .driver_data in drivers that don't use this member
is silly and a bit irritating. Drop these. Also simplify the list
terminator entry to be just empty to match what most other device_id
tables do.

There is no changed semantic, not even a change in the compiled result.
