Rebuild the aic7xxx firmware doesn't work anymore after this change
which appeared int 2.6.13-rc1:

   [SCSI] aic7xxx/aic79xx: remove useless byte order macro cruft

Two files did not include byteorder.h, resulting in aic dying with a panic

	"Unknown opcode encountered in seq program"

This fixes it for me.
