* Get rid of calibration timer, instead use a software interrupt

a) We don't need a timer for this, there is no need for accuracy
even with round_jiffies i think this is a waste of resources.
Also we don't need to run calibration if we are idle (no
interrupts).
b) When we add ANI support we 'll just extend the poll function
and calibration tasklet and handle all periodic phy calibration
on one place (much cleaner).
c) Having calibration on a tasklet is better since during calibration
we can't transmit or receive (antennas are detached to measure
noise floor), previously calibration could run in parallel with
tx/rx and interfere (packet loss).

The patch "Implement set_tim callback for all drivers" can cause kernel
oops in rt73usb_write_beacon. The oops is caused by one of the following
race conditions:
* In case of two near calls to set_tim: rt2x00lib_beacondone_iter is
cleaning the beacon skb, whereas rt73usb_write_beacon is still using it.
* In case of two near updates of beacon: first as the result of set_tim
and second as the result of a call from an application (e.g. hostapd).
This patch fixes the race condition by rearranging the update logic and

Depending on required latency requested by pm_qos (via mac80211)
we can automatically adjust the sleep state. Also, mac80211 has
a user-visible dynamic sleep feature where we are supposed to
stay awake after sending/receiving frames to better receive
response frames to our packets, this can be integrated into the
sleep command.
Currently, and this patch doesn't change that yet, we default
to using sleep level 1 if PS is enabled. With a module parameter
to iwlcore, automatic adjustment to changing network latency
requirements can be enabled -- this isn't yet the default due
to requiring more testing.
The goal is to enable automatic adjustment and then go into the
deepest possible sleep state possible depending on the networking
latency requirements.
This patch does, however, enable IEEE80211_HW_SUPPORTS_DYNAMIC_PS
to avoid the double-timer (one in software and one in the device)
when transmitting -- the exact timeout may be ignored but that is
not of big concern.
Note also that we keep the hard-coded power indices around for
thermal throttling -- the specification of that calls for using
the specified power levels. Those can also be selected in debugfs
to allow easier testing of such parameters.

commit "iwlwifi: uCode Alive notification with timeout" introduced a more
reliable mechanism for ucode loading. Unfortunately we hit a problem with
it frequently enough to make a 4965 unusable. The problem can be seen in
debug log below. What this code attempts is to set runtime ucode up to
load, start a timer to wait for the alive response from runtime ucode, and
if it times out it tries again. As can be seen below we receive the alive
response and wake the waiting task _before_ the tasks starts waiting. The
task thus times out as the alive response is not received while it is
waiting for it and it restarts the device. This starts the cycle all over
again.
