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.

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.

as they are actualy used for the upcoming auto ACK support.

There is no need to implement empty suspend/resume callbacks if there is nothing
to do during suspend/resume. The drivers will behave the same with no callbacks
or empty callbacks during suspend/resume.

CONFIG_HOTPLUG is going away as an option.  As result the __dev*
markings will be going away.

Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst,
and __devexit.

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.

The code under _init and _exit functions is similar to the code of
module_spi_driver macro, which is a wrapper to the module_driver macro,
so use it instead.

The AT86RF231 is a feature rich, low-power 2.4 GHz radio transceiver
designed for industrial and consumer ZigBee/IEEE 802.15.4, 6LoWPAN,
RF4CE and high data rate 2.4 GHz ISM band applications.

This patch adds support for the Atmel RF230/231 radio transceivers.
