Modify ath_descdma_setup() to take a descriptor size parameter.

The AR9300 and later descriptors are 128 bytes, however I'd like to make
sure that isn't used for earlier chips.

* Populate the TX descriptor length field in the softc with
  sizeof(ath_desc)

* Use this field when allocating the TX descriptors

* Pre-AR93xx TX/RX descriptors will use the ath_desc size; newer ones will
  query the HAL for these sizes.
