[SCSI] aic byteorder fixes after recent cleanup

 aic doesnt work anymore after this change which appeared int 2.6.13-rc1:
 [SCSI] aic7xxx/aic79xx: remove useless byte order macro cruft

 2 files did not include byteorder.h, aic died with panic
 "Unknown opcode encountered in seq program"
 This patch fixes it for me.
