Subject: mac80211: change MIMO_PS to SM_PS

This patch follows 11n spec naming more rigorously replacing MIMO_PS
with SM_PS (Spatial Multiplexing Power Save).

(Originally submitted as 4 patches, "mac80211: change MIMO_PS to SM_PS",
"iwlwifi: change MIMO_PS to SM_PS", "ath9k: change MIMO_PS to SM_PS",
and "iwlwifi: remove double definition of SM PS". -- JWL)

Subject: iwlwifi: use the results from disconnected antenna algorithm

This patch makes usage of the results from disconnected antenna alg to
know how many antennas are connected.

It also synchronizes between the chain noise alg and the W/A that
disables power management during association. All the antennas must be
enables during the chain noise algorithm. Hence, power management is
restored only after the completion of the algorithm.

In the future, we will need to update the AP that we don't support MIMO
if there is only one antenna connected. We also need to update the rate
scaling algorithm.

Subject: iwlwifi: remove uneeded declarations

This patch cleans up iwlwifi by removing uneeded declarations and removing
uneeded symbol export reducing the namespace pollution. It also fixes some
typos in comments.

Subject: p54: 32-bit tsf timestamps

tcpdump:
02:15:42.874518 61112184us tsft 48.0 Mb/s 2437 MHz (0x0480) antenna 1 [0x0000000e] CF +QoS Data IV
02:15:42.874557 >>>4356079526us<<< tsft 24.0 Mb/s 2437 MHz (0x0480) antenna 1 [0x0000000e] Acknowledgment
02:15:42.976844 61214513us tsft 1.0 Mb/s 2437 MHz (0x0480) antenna 0 [0x0000000e] Beacon

as one can see on the huge jump, it's very plausible that firmware does not report the
full 64-bit mac time, just the lower 32bit and some kinds of flags...
Therefore if we want a useful timestamp we have to emulate the high bits.
