ath9k: merge noisefloor load implementations
AR5008+ and AR9003 currently use two separate implementations of the
ath9k_hw_loadnf function. There are three main differences:
- PHY registers for AR9003 are different
- AR9003 always uses 3 chains, earlier versions are more selective
- The AR9003 variant contains a fix for NF load timeouts
This patch merges the two implementations into one, storing the
register array in the ath_hw struct. The fix for NF load timeouts is
not just relevant for AR9003, but also important for earlier hardware,
so it's better to just keep one common implementation.

wl1271: Work around AP's with broken ps-poll functionality
Some AP's (such as Zyxel Prestige 600) have totally broken ps-poll
functionality. When powersave is enabled, these AP's will set the TIM bit for
a STA in beacons, but when the STA responds with a ps-poll, the AP does not
respond with data.
The wl1271 firmware is able to send an indication to the host, when this
problem occurs. This patch adds implementation, which temporarily disables
power-save in response to this indication, allowing the AP to transmit whatever
data it has buffered for the STA / whatever data is inbound at that time.
This patch does not make these AP's work reliably in PSM, but improves the
chances of inbound data getting through.
The side effect of this patch is increased power consumption when using a
faulty AP.

rt2x00: Remove unneeded variable
The update_bssid is set only when BSS_CHANGED_BSSID is used,
but the check if that field is true is done later in the function
but also only when BSS_CHANGED_BSSID is set. This makes the
variable useless, as it can never result in a negative check.

rt2x00: Write the BSSID to register when interface is added
For the Master mode case, we initialized the BSSID as the MAC
address, but never wrote it into the registers. This causes
Hardware crypto to break in Master mode when receiving frames
which require the BSSID to be filled in.
This is safe for STA mode since the BSSID will be initialized
to 00:00:00:00:00 at this point, but will be set to the correct
value later when the device associates.
