So you should ideally set this to whatever the hardware engineers should have used, had they paid attention to detail. If your company has a contact point at JEDEC they should know which implementer ID to use for Ambarella designs. Since Ambarella is evidently a member of JEDEC your representative should be able to simply request a JEP106 implementer ID and give it to you if there is not one assigned already, but I know it can be hard sometimes to find the right person inside the company but I think it'd be worth going the extra mile here, say that this guy from the kernel community persists.
