Add option to at86rf230 platform data to configure the type of the
interrupt used by the driver. The irq polarity of the device will
be configured accordingly.

On the MRF24J40, link-layer acknowledgment request and retry must be
turned on explicitly for each packet.  Turn this on in the hardware based
on the FC_ACK_REQ bit being set in the packet.

Also, now that failure to receive an ACK will cause the hardware to report
failure of transmission, change the log level for this failure to debug
level.

In at86rf230_probe() lp was first set to dev->priv and a few lines later
dev->priv was set to lp again, without changing lp in between. The call
to ieee802154_unregister_device() before err_irq: was unreachable.

It served no purpose: we never call it from anywhere in the stack
and the only driver that did implement it (fakehard) merely provided
a dummy value.

There is also considerable doubt whether it would make sense to
even attempt beacon processing at this level in the Linux kernel.

Use the wrapper functions for getting and setting the driver data using
spi_device instead of using dev_{get|set}_drvdata with &spi->dev, so we
can directly pass a struct spi_device.

The network merge brought in a few users of functions that got
deprecated by the workqueue cleanups: the 'system_nrt_wq' is now the
same as the regular system_wq, since all workqueues are now non-
reentrant.

Similarly, remove one use of flush_work_sync() - the regular
flush_work() has become synchronous, and the "_sync()" version is thus
deprecated as being superfluous.

The IEEE 802.15.4 standard represents a networking protocol. I don't
exactly know why drivers for this protocol are stored into the root
'driver' folder, but better will be to store them with other
networking stuff. Currently there are only 3 drivers available for
IEEE 802.15.4 stack, so lets do it now with the smallest overhead.
