From: Bruno Randolf <br1@xxxxxxxxxxx>
* make struct ath5k_desc clearer by directly including unions of structures,
which correspond to the hardware descriptors of different HW versions (5210
and 5212). before they were casted at onto ath5k_desc at different points
(e.g. ds_hw[2]).
* rename some structures and variable names to make their use clearer, e.g.
struct ath5k_hw_4w_tx_desc to ath5k_hw_4w_tx_ctl.
* substitute "old" with "5210" and "new" with "5212" (eg. rename
ath5k_hw_proc_new_rx_status() to ath5k_hw_proc_5212_rx_status()) because old
and new are relative and we might have a newer structure at some point.
* unify structs ath5k_hw_old_rx_status and ath5k_hw_new_rx_status into one
ath5k_hw_rx_status, because they only differ in the flags and masks.
