Fine, OK, here's my initial AR9380/AR9485 support

[Adrian Chadd]

I've just fixed a couple things with the AR9300 HAL:

* I've implemented a "get slot time" method, so one stub function call
message should disappear;
* I've fixed a quirk with slot/ack/rtscts timeout calculations in HT40
- the AR9300 HAL was compensating for the 40Mhz width of the channel,
but FreeBSD's HAL library call already does this. So now the HAL
doesn't double compensate for this.
* I broke and then fixed some compile time issues.

Please update and test!

Thanks,


Adrian
