The 0x41 in ARMs PeriphID is actually the JEDEC JEP106
implementer ID (8 bits).

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.
