Diff reduction to Adaptec driver build 15317 (refactoring and code shuffling):
- Resource allocation in aac_alloc (moved from from aac_init) - Interrupt setup in aac_setup_intr (from aac_attach) - Container probing in aac_get_container_info (from aac_startup and aac_handle_aif) - Firmware status check moved to aac_check_firmware from aac_init
