The driver tx-queue flush operation leaks broadcast-frames. This leak occurs
if the driver is shut down while there are frames in TX buffers (such as in
a firmware crash scenario.) Fix the leak.

Change the driver to call ieee80211_beacon_loss function always when
BSS_LOST_EVENT is received. Reason for the change is that entering PSM
might fail before driver receives BSS_LOST_EVENT. In such case the
driver would disable PSM and the stack would not be notified about beacon
loss and connection loss detection would be delayed by tens of seconds.

The wl1271 does not support disabling the connection monitor feature.
Perform the next best thing by increasing the beacon-loss threshold and
BSS_LOSE event timeout to the maximum values.

This is needed, because we really don't want any random probe-requests during
scanning or especially while in ad-hoc mode and not beaconing.

After the busy-words, if the firmware did not complete by the end of the
first (fixed) busy-word, a flip of the CS line is required to enable clocking
out the actual read data.

This patch changes the mechanism such that the CS line is flipped after each
busyword.

Also, the busy-word mechanism is finally enabled, and the number of fixed
busywords reduced to the minimum.

Chipsets since revision AR5213A (0x59) have hardware counters for PHY errors
which we can read directly from the registers. Older hardware has to use the RX
