Can we relook into this series? 
AFA EXYNOS9_ macro is concern, Exynos990, Exynos9810 etc already support available upstream.
Of course it does not justify why Exynos9, but we can consider all SoCs which has come after 2020 have this newer architecture. 
Or Just have SAMSUNG_ prefix for all such newer SoC.

A unified Macro help in adding new SoC support without much confusion(like I am trying with Exynos8855)

@Youngmin, will you have some time to re-spin these series?
