Begin some dirty hacks to implement channel survey support and unify
some of the MIB counter access.

The reference HAL has a handful of routines which fondle the MIB
registers. This commit modifies the ar5416AniGetListenTime() to use
ar5416GetMibCycleCountsPct() which grabs the TX/RX/RC counters and
returns the percentage of time the channel is busy. This way it doesn't
also do its own register reading.

The last values are cached in the ath_hal state, so they can be used
by other parts of the code. This will (eventually) include channel
survey support, which will keep a per-channel history of these values.

Also - run this every ANI interval, whether it's enabled or not.
The listen time routine should be modified to not use ANI state at all
so it can be called if it's disabled without the fear of aniState
being NULL, but that can come in a subsequent commit.
