iwlwifi: make sure device is reset when unloading driver
Add unconditional call to apm_ops.stop() to reset device to low power state
when unloading driver. Some paths have existed to unload driver *without*
resetting device, therefore some errors have persisted through multiple
load/unload cycles, until the whole platform gets rebooted; this is an
attempt to remedy some of those situations. Sorry, I can't seem to find
a bughost.org bug that specifically has these symptoms, but I had it happen
recently here.
Note that this will *not* fix situations in which the PCI express bus has
crashed (evidenced by register reads showing "0xffffffff"), e.g. bughost.org
1855 and 2096; device is unreachable from driver in those cases.

First, we reduce the number of hardware retries to 0 (ie 2 real retries

report a retry count of 1 (it seems to be 2 in fact, but using 2 seems
to lead to wrong performance for some reason). We use a state machine to
determine the real fate of a packet based on the 802.11 ACK and what the
Zydas hardware is saying when a real retry occurs. The real retry rates
are encoded in a static array. It has been tested with both zd1211 and
zd1211b hardware. Of course, since the Zydas hardware is not reporting
retries accurately, we are just doing our best in order to get the best

Also, all the struct definitions for data exchanged with the firmware has
been changed to use __le16/32 types instead of u16/32.

Replace netif_tx_{start,stop,wake}_all_queues with the single-queue
equivalents (i.e. netif_{start,stop,wake}_queue). Since we are down to
a single queue, these should peform slightly better.

ath5k: use noise calibration from madwifi hal
This updates ath5k to calibrate the noise floor similar to the
way it is done in the madwifi hal and ath9k. Of note:
- we start NF measurement at the same time as AGC calibration,
but do not actually read the value until the periodic (long)
calibration
- we keep a history of the last few values read and write the
median back to the hardware for CCA
- we do not complain if NF calibration isn't complete, instead
we keep the last read value.

We cannot be in PS mode when running PLT tests, so we need to make sure we're
