ath10k: add fast peer_map lookup

Browse source

The pull-push functionality of 10.4 will be based
on peer_id and tid. These will need to be mapped,
eventually, to ieee80211_txq to be used with
ieee80211_tx_dequeue().

Iterating over existing stations every time
peer_id needs to be mapped to a station would be
inefficient wrt CPU time.

The new firmware, which will be the only user of
the code flow-wise, will guarantee to use low
peer_ids first so despite peer_map's apparent huge
size d-cache thrashing should not be a problem.

Older firmware hot paths will effectively not use
peer_map.
