[SCSI] aic7xxx: Remove OS utility wrappers

This patch removes malloc(), free(), and printf() wrappers from the aic7xxx
SCSI driver. I didn't use pr_debug for printf because of some 'clever' uses of
printf don't compile with the pr_debug. I didn't fix the overeager uses of
GFP_ATOMIC either because I wanted to keep this patch as simple as possible.
