This patch does 3 things

1) It removes the statistics work. The request statistics command is
sent in ASYNC mode in this flow, the mutex is uneeded, so the request
statistics function can't go to sleep. No need for a workqueue anymore.

2) iwl4965_send_statistics_request has been renamed to
iwl_send_statistics_request and moved to iwl-core.c

3) A request for statistics is sent in alive_notify, the makes the uCode
sends statistics notification periodically starting from association.

This adds a fastpath for the common workloads to the
MAC suspend flushing.
In common workloads the FIFO flush will take between 100 and
200 microseconds. So we want to avoid calling msleep() in the
common case, as it will waste over 800 microseconds + scheduler
overhead.

This fastpath will hit in workloads where only small chunks
of data are transmitted (downloading a file) or when a TX rate bigger
or equal to 24MBit/s is used when transmitting lots of stuff (iperf).
So in the commonly used workloads it will basically always hit.

In case the fastpath is not hit, there's no real performance or latency
disadvantage from that.

And yes, I measured this. So this is not one of these
bad Programmer Likeliness Assumptions that are always wrong. ;)

Do not use workqueue for bss_info_changed post association work.
When driver is notified of association the upper layer will be notified
right after that the association is complete. Doing the post association
work in a workqueue introduces a race condition where the upper layer may
want to make use of the association, but it is not yet complete.

This patch (co-developed by Dan Williams and Holger Schurig) uses a kfifo
object for events and a swapping buffer scheme for the command response to
preserve the zero-copy semantics of the CF driver and keep memory usage low.
The main thread should only ever touch the buffer indexed by priv->resp_idx,
while the interface code is free to write to the second buffer, then swap
priv->resp_idx under the driver spinlock.  The firmware specs only permit
one in-flight command, so there will only ever be one command response to
process at a time.

In rt2x00lib_intf_scheduled_iter() we use the hw->beacon_update()
callback function. This means that it should behave similarly as mac80211
when that uses the function.

This means that the skb should only be freed when beacon_update() has failed,
otherwise the driver is the owner and is responsible for freeing the buffer.

This fixes DMA on architectures where DMA is nontrivial, like PPC64.
We must use the host-device's (PCI) struct device for any DMA
operation instead of the SSB device. For this we add a new
struct device pointer to the SSB device structure that will always
point to the right device for DMAing.

Without this patch b43 and b44 drivers won't work on complex-DMA
architectures, that for example need dev->archdata for DMA operations.
