We were using CONF_TX_RATE_MASK_ALL when calling wl1271_acx_rate_policies()
during init. We should use WL1271_DEFAULT_BASIC_RATE_SET instead. The
values are the same, but the latter is just the correct macro to use.

Now we're using a the idle information coming from mac80211 to decide when to
disconnect. If we have joined (ie. we're listening to a channel), whenever
the interface goes to idle, we will issue a disconnect command. So the
workaround to send a disconnect command before joining is not needed anymore.

When we need to change the channel before association, we have to send a join
command with a valid BSSID. With this patch we use 0baddeadbeef as the
BSSID. There are ongoing discussions with TI to get this done in a cleaner
way.
When we go back to idle, we issue a CMD_DISCONNECT to make sure the firmware
stops listening to the channel and cleans things up internally.

If userencounter the "Fatal DMA Problem" with a BCM43XX device, and
still wish to use b43 as the driver, their only option is to rebuild
the kernel with CONFIG_B43_FORCE_PIO. This patch removes this option and
allows PIO mode to be selected with a load-time parameter for the module.
Note that the configuration variable CONFIG_B43_PIO is also removed.
Once the DMA problem with the BCM4312 devices is solved, this patch will
likely be reverted.

The receive descriptor ops that are currently marked as being for
8687 only are actually used for all STA firmware images, whereas the
receive descriptor ops marked as 8366 are only used on 8366 when an
AP firmware image is in use.
Rename the receive descriptor ops to reflect this, use the STA ops
unconditionally if the firmware image loaded reported the STA ready
code, and rename the mwl8k_device_info::rxd_ops member to ap_rxd_ops
to indicate that it should only be used if we are running on AP

a bug there -- if allocation/insertion fails then it is
possible that we are left in a lingering state where
mac80211 waits for the AP, cfg80211 waits for mac80211,
but the AP has already replied. Since there's no way to
indicate an internal error, pretend there was a timeout,
i.e. that the AP never responded.

cfg80211: remove warning in deauth case
we assumed that drivers never give us spurious deauth
frames because they filter them out based on the auth
state they keep track of. This turned out to be racy,
because userspace might deauth while the AP is also
sending a deauth frame, so the warning was removed.
However, in that case we should not tell userspace
about the AP's frame if it requested deauth "first",
where "first" means it came to cfg80211 first.
