Quick look tells me you just duplicated existing Samsung ChipID driver.
Even actual product ID registers and masks are the same, with one
difference - you read CHIPID3... which is the same as in newer Exynos,
e.g. Exynos8895.

What is exactly the point of having this as separate driver? I think
this can easily be just customized chipid driver - with different
implementation of exynos_chipid_get_chipid_info().
