WoWLAN may need the NIC even after suspend. One should not do anything to the
NIC in the bus level, since one cannot check whether WoWLAN is enabled or not.
Same for resume.
Add a simple comment to the code to warn about this.

The price to pay is the access to the log system. Therefore logs from bus layer
are sent by dev_printk instead of IWL_XXXX.
Rename bus->priv to bus->drv_data to make the separation even clearer.

Call iwl_probe with a ready iwl_bus struct. This means that the bus layer
assigns the irq, dev and iwl_bus_ops pointers to iwl_bus before giving it to
iwl_probe.
The device specific struct is allocated together with the common iwl_bus struct
by the bus specific layer. The pointer to the aggregate struct is passed to the
upper layer that holds a pointer to iwl_bus instead of an embedded iw_bus.
The private data given to the PCI subsystem is now iwl_bus and not iwl_priv.
Provide bus_* inliners on the way in order to simplify the syntax.
Rename iwl-pci.h -> iwl-bus.h since it is bus agnostic and represent the
external of the bus layer.

It still holds a pointer to iwl_priv. But hopefully this will disappear at some point.
Also add the multiple inclusion protection to iwl-trans.h that was forgotten.

Both ath5k_hw and ath5k_softc represent one instance of the hardware.
This duplication is historical and is not needed anymore.
Keep the name "ath5k_hw" for the merged structure and "ah" for the
variable pointing to it. "ath5k_hw" is shorter than "ath5k_softc", more
descriptive and more widely used.
Put the combined structure to ath5k.h where the old ath5k_softc used to
be. Move some code from base.h to ath5k.h as needed.
Remove memory allocation for struct ath5k_hw and the corresponding error
handling. Merge iobase and ah_iobase fields.

Harshal Chhaya discovered during network tests, that
several of his clients dropped-off the network. The
captured packets shows that the beacons sent by the
AP are at a much lower power than the other data
packets.
The reason for this mishap: The driver never updated
the beacon phy register, so all beacons were always
sent at the lowest power.
