ALSA: ppc: keywest: Drop explicit initialization of struct i2c_device_id::driver_data to 0

The driver doesn't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.

This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.
