ath5k: Reset cleanup and generic cleanup
* No functional changes * Clean up reset: Introduce init functions for each unit and call them instead of having everything inside ath5k_hw_reset (it's just c/p for now so nothing changes except calling order -I tested it with various cards and it's ok-) * Further cleanups: ofdm_timings belongs to phy.c rate_duration belongs to pcu.c clock functions are general and belong to reset.c (more to follow) * Reorder functions for better organization: We start with helpers and other functions follow in categories, init functions are last Signed-off-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W.
