[ath_hal] Don't do ANI processing if we've reset.

If we've reset then we can't trust the current state of the ANI tracking,
so just wait until next time.

Tested:

* AR5424, STA mode (2GHz)

Start the process of migrating the ANI statistics out of the HALs and into
the top-level HAL.

The athstats program is blindly using a copy of the ar5212 ANI stats structure
to pull out ANI statistics/state and this is problematic for the AR9300
HAL.

So:

* Define HAL_ANI_STATS and HAL_ANI_STATE
* Use HAL_ANI_STATS inside the AR5212 HAL

This commit doesn't (yet) convert the ar5212AniState -> HAL_ANI_STATE when
exporting it to userland; that'll come in the next commit.

Move the HAL channel survey support out to be in the top-level HAL,
rathe than private in each HAL module.

Whilst here, modify ath_hal_private to always have the per-channel
noisefloor stats, rather than conditionally. This just makes
life easier in general (no strange ABI differences between different
HAL compile options.)

Add a couple of methods (clear/reset, add) rather than using
hand-rolled versions of things.

Add channel survey support to the AR5212 HAL.

The AR5212 series of MACs implement the same channel counters as the
later 11n chips - except, of course, the 11n specific counter (extension
channel busy.)

This allows users of these NICs to use 'athsurvey' to see how busy their
current channel is.

Tested:

* AR5212, AR2413 NICs, STA mode

Fix ANI handling to work correctly when (trying) to receive radar errors.

* Teach the AR5212/AR5416 ANI code to use the RX filter methods, rather
than calling the RX filter routines directly.

* Make HAL_ANI_PRESENT and HAL_ANI_MODE unconditionally available,
regardless of whether ah_ani_function is masking it.

* (Mostly) fully disable ANI if interference mitigation is disabled.
When disabled, the ANI code doesn't touch any ANI/PHY registers,
leaving them the default value. This is in line with what the
Atheros reference driver does.

* Correctly set the ANI parameters during ANI reset, rather than
when ANI is enabled. In this way, if ANI is disabled or enabled
whilst the NIC is not active (and there's no current channel),
bogus parameters or a NULL pointer deference doesn't occur.

There's still some lingering issues - notably, the MIB events/interrupts
aren't fully disabled, so MIB interrupts still occur. I'll worry about
that later.

ANI changes #1 - split out the ANI polling from the RxMonitor hook.

The rxmonitor hook is called on each received packet. This can get very,
very busy as the tx/rx/chanbusy registers are thus read each time a packet
is received.

Instead, shuffle out the true per-packet processing which is needed and move
the rest of the ANI processing into a periodic event which runs every 100ms
by default.
