OK, renaming the driver and it's config options is not the best idea.
But how about renaming the variables and function names within the drivers?
It would be more clearer which driver parts are generic and are used by
multiple PMIC devices.

It seems this topic has been already discussed here [1].
So the right solution is just to rename the rk808 struct in rk808.h,
don't touch the driver names and config options and naming the
additional RK818 PMIC in the Kconfig?
