wl12xx: use 1 spare TX block instead of two
All the new firmware versions (>=6.1.3.50.58 for STA and >=6.2.0.0.47
for AP) use 1 spare TX block. We still want to support older
firmwares that require 2 spare blocks, so added a quirk to handle the
difference.
Also implemented a generic way of setting quirks that depend on the
firmware revision.
