Break out the TX descriptor link field into HAL methods.

Browse Source 
The DMA FIFO chips (AR93xx and later) differ slightly to th elegacy
chips:

* The RX DMA descriptors don't have a ds_link field;
* The TX DMA descriptors have a ds_link field however at a different
  offset.

This is a reimplementation based on what the reference driver and ath9k
does.

A subsequent commit will enable it in the TX and beacon paths.
