ath5k: review and add comments for descriptors
I carefully reviewed desh.h against the HAL sources. Added comments and made differences between 5210, 5211 and 5212 more clear by adding _521x to the defines which are specific to that chipset. Renamed some defines. No functional changes. Signed-off-by: Bruno Randolf <br1@einfach.org> Acked-by: Bob Copeland <me@bobcopeland.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
