ath(4) ALQ logging improvements.

* Add a new method which allows the driver to push the MAC/phy/hal info
  into the logging stream.
* Add a new ALQ logging entry which logs the mac/phy/hal information.
* Modify the ALQ startup path to log the MAC/phy/hal information
  so the decoder knows which HAL/chip is generating this information.
* Convert the header and mac/phy/hal information to use be32, rather than
  host order.  I'd like to make this stuff endian-agnostic so I can
  decode MIPS generated logs on a PC.

This requires some further driver modifications to correctly log the
right initial chip information.

Also - although noone bar me is currently using this, I've shifted the
debug bitmask around a bit.  Consider yourself warned!
