ath(4): begin fleshing out a "reset type" extension to force cold/warn resets.

Right now the only way to force a cold reset is:

* The HAL itself detects it's needed, or
* The sysctl, setting all resets to be cold.

Trouble is, cold resets take quite a bit longer than warm resets.

However, there are situations where a cold reset would be nice.
Specifically, after a stuck beacon, BB/MAC hang, stuck calibration results,
etc.

The vendor HAL has a separate method to set the reset reason (which is
how HAL_RESET_BBPANIC gets set) which informs the HAL during the reset path
why it occured. This is almost but not quite the same; I may eventually
unify both approaches in the future.

This commit just extends HAL_RESET_TYPE to include both status (eg BBPANIC)
and type (eg do COLD.) None of the HAL code uses it yet though; that'll
come later.

It also is a big no-op in each HAL - I need to go teach each of the HALs
about cold/warm reset through this path.

Disable WEP hardware encryption on the AR5210, in order to allow other
encryption types.

The AR5210 only has four WEP key slots, in contrast to what the
later MACs have (ie, the keycache.) So there's no way to store a "clear"
key.

Even if the driver is taught to not allocate CLR key entries for
the AR5210, the hardware will actually attempt to decode the encrypted
frames with the (likely all 0!) WEP keys.

So for now, disable the hardware encryption entirely and just so it
all in software. That allows both WEP -and- WPA to actually work.

If someone wishes to try and make hardware WEP _but_ software WPA work,
they'll have to create a HAL capability to enable/disable hardware
encryption based on the current STA/Hostap mode. However, making
multi-vap work with one WEP and one WPA VAP will require hardware
encryption to be disabled anyway.

Stop using the hardware register value byte order swapping for now,
at least until I can root cause what's going on.

The only platform I've seen this on is the AR9220 when attached to
the AR71xx CPUs. I get immediate PCIe bus errors and all subsequent
accesses cause further MIPS bus exceptions. I don't have any other
big-endian platforms to test this on.

If I get a chance (or two), I'll try to whack this on a bus analyser
and see exactly what happens.

I'd rather leave this on, especially for slower, embedded platforms.
But the #ifdef hell is something I'm trying to avoid.
