8b0be90c4d b43/legacy: Remove firmware IDs
This removes the "FWxx" ID strings from the b43 and b43legacy
drivers. They were once used to match a specific driver revision
to a set of firmware files. However, this is hardly useful today.
Additionally, the IDs are not updated and maintained properly, so
they might mislead users.

8ad38d22dc ath9k_hw: Disable Walsh spatial spreading for 2 chains
The Walsh bit is disabled for regulatory consideration.

FCC limit for walsh enable is lower than that for walsh disable. So
disabling walsh bit will not limit tx power/affect tx power even in
cases where we are not FCC limited (most client cards). If the tx
power is not FCC limited, then enabling/disabling walsh bit will
not affect Avg. EVM/overall performance in any visible manner.

a35e278022 ath9k: Change rate control to use legacy rate as last MRR
In congested network, having all rate reties at MCS rates
is failing to transmit the frame offenly. By the time reaching
the success rate set, the application gets timed out. One such
scenario is that authentication time out during 4-Way handshake.
This patch uses a legacy rate as last retry sequnce for
unaggregated frames or if the first selected rate's PER is ~80%
of max limit. And also observed from the tx status that the frame
was trasmitted successfully by using legacy rates.
