This patch contains the following possible cleanups:
- make needlessly global code static
- #if 0 the following unused global functions:
- aic79xx_core.c: ahd_print_scb
- aic79xx_core.c: ahd_suspend
- aic79xx_core.c: ahd_resume
- aic79xx_core.c: ahd_dump_all_cards_state
- aic79xx_core.c: ahd_dump_scbs
