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.

iwlwifi: use paged Rx
This switches the iwlwifi driver to use paged skb from linear skb for Rx
buffer. So that it relieves some Rx buffer allocation pressure for the
memory subsystem. Currently iwlwifi (4K for 3945) requests 8K bytes for
Rx buffer. Due to the trailing skb_shared_info in the skb->data,
alloc_skb() will do the next order allocation, which is 16K bytes. This
is suboptimal and more likely to fail when the system is under memory
usage pressure. Switching to paged Rx skb lets us allocate the RXB
directly by alloc_pages(), so that only order 1 allocation is required.
It also adjusts the area spin_lock (with IRQ disabled) protected in the
tasklet because tasklet guarentees to run only on one CPU and the new
unprotected code can be preempted by the IRQ handler. This saves us from
spawning another workqueue to make skb_linearize/__pskb_pull_tail happy
(which cannot be called in hard irq context).
Finally, mac80211 doesn't support paged Rx yet. So we linearize the skb
for all the management frames and software decryption or defragmentation
required data frames before handed to mac80211. For all the other frames,
we __pskb_pull_tail 64 bytes in the linear area of the skb for mac80211
to handle them properly.

iwlwifi: turn off device when not used.
In some cases (e.g. when mac80211 calls iwl_mac_stop() for suspend or user
no longer wants device active), device has not been going into low power state
via __iwl_down(). apm_ops.reset() does not put device into low power state;
instead it resets the device, then puts it into a powered-up state ready to be
re-loaded with uCode and re-started. This has needlessly warmed up user's
laptops and drained batteries.
With current architecture in which mac80211 controls device up/down (including
resetting device after firmware errors), there is no need for apm_ops.reset()
any more; apm_ops.reset() is basically a combination of apm_ops.stop() and
apm_ops.init().
Instead, __iwl_down() now unconditionally places the device into a low-power
state via apm_ops.stop(). Device may be re-started via __iwl_up() calling
apm_ops.init() as soon as it may be needed (e.g. quickly for firmware errors),
but in the meantime, device will stop wasting energy.
Note that, even in this low power state, if driver re-enables interrupts,
the device retains the ability to sense the hardware RF-KILL switch, and
(except for 3945) interrupt the host when it changes.

wl1271: remove unecessary qual parameter from rx status
The qual element in ieee80211_rx_status is not used anymore, so we don't need
to set it in the wl1271_rx_status() function. This saves a bit of time in
the RX path.

The PA calibration for ar9271 ath9k_hw_9271_pa_cal() can run during
reset or initial calibration, update the PA calibration to account
for that and initialize PA calibration variables for both conditions.

sfc: Rename 'xfp' file and functions to reflect reality
The 'XFP' driver is really a driver for the QT2022C2 and QT2025C PHYs,
covering both more and less than XFP. Rename its functions and
constants to reflect reality and to reduce namespace pollution when
sfc is a built-in driver.

sfc: Move MTD probe after netdev registration and name allocation
The MTD partition is named based on the netdev name, which is set to
'eth%d' before registration. Also, the MTD partition will currently
be left registered if netdev registration fails.
Fix both these problems by moving the MTD probe after netdev
registration. Hold the RTNL to serialise this with the netdev
notifier that calls efx_mtd_rename().
