The current assumption of IS_V6 is overgeneralized. Adjust the logic
to take the VPU hardware version into account.

I think the IRIS1 check can be removed from here as we are not handling IRIS1 related things at other places.

we can add the required checks for IRIS1 when we add support for any IRIS1 based chipset.
Up to you really, I plan on getting IRIS1 (SM8150) supported and have
some mumbling going on for that on my local branch. FWIW these checks
are logically correct and I would personally prefer not to have to go
through each one of them and remove them just to bring them back soon.

oh, I see. I wasn't aware about the plan for IRIS1.

if you plan to add these checks on all relevant places then it should be fine.

Thanks,
