This patch adds rudimentary a-hoc support for the driver. It will allow
setting up ad-hoc, and for other devices to scan and join. The beacon and probe
response template setting is slightly dirty, and need to be properly
implemented with support from mac80211. Also, the SSID is not configured to the
firmware - the FW will not be able to respond to probe requests autonomously.

This patch adds a short delay before powering on the wl1271. Normally, it is

Note that the configuration variable CONFIG_B43_PIO is also removed.

The receive descriptor ops that are currently marked as being for

Rename the receive descriptor ops to reflect this, use the STA ops
unconditionally if the firmware image loaded reported the STA ready
