iwl3945: synchronize timestamp with uCode
In IBSS, TSF maintains local clock counters at each station. Network
Synchronization follows a completely distributed scheme where beacon frames
are generated. Each station maintain its own TSF timestamp, extracted from
beacon timestamps they recieved. Following patch synchronize this beacon timestamp
with uCode.
