Both ath5k_hw and ath5k_softc represent one instance of the hardware.
This duplication is historical and is not needed anymore.
Keep the name "ath5k_hw" for the merged structure and "ah" for the
variable pointing to it. "ath5k_hw" is shorter than "ath5k_softc", more
descriptive and more widely used.
Put the combined structure to ath5k.h where the old ath5k_softc used to
be. Move some code from base.h to ath5k.h as needed.
Remove memory allocation for struct ath5k_hw and the corresponding error
handling. Merge iobase and ah_iobase fields.
