Some debugging tools require the chip to be powered on before they can work.
With these tools, we shouldn't upload the firmware nor boot the firmware
ourselves, so this debufs file is provided. It always contains the gpio
power setting (0 = off, 1 = on). To change the power setting, just write 0
or 1 to the file.

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
firmware.

My previous change added in:
commit 815833e7ecf0b9a017315cae6aef4d7cd9517681
ath9k: fix tx status reporting
was not checking all possible tx error conditions. This could possibly
lead to throughput issues due to slow rate control adaption or missed
retransmissions of failed A-MPDU frames.
This patch adds a mask for all possible error conditions and uses it
in the xmit ok check.

The calibration period is now invoked by triggering a software
interrupt from within the ISR by ath5k_hw_calibration_poll()
instead of via a timer.
However, the calibration interval isn't initialized before
interrupts are enabled, so we can have a situation where an
interrupt occurs before the interval is assigned, so the
interval is actually negative. As a result, the ISR will
arm a software interrupt to schedule the tasklet, and then
rearm it when the SWI is processed, and so on, leading to a
softlockup at modprobe time.
Move the initialization order around so the calibration interval
is set before interrupts are active. Another possible fix
is to schedule the tasklet directly from the poll routine,
but I think there are additional plans for the SWI.
