KS8851: Add soft reset at probe time

Issue a full soft reset at probe time.

This was reported by Doong Ping of Micrel, but no explanation of why this is necessary or what bug it is fixing. Add it as it does not seem to hurt the current driver and ensures that the device is in a known state when we start setting it up.
