This platform has its own kernel defconfig in Buildroot, but we cannot
get quick idea about how much it diverged from the in-kernel defconfig.

Let's use the upstream arch/arm/config/versatile_defconfig as a base,
and maintain the diff as a merge-config fragment. The same .config is
still generated based on the 5.10.7 kernel.

The diff is quite big, but this is a good start-point for cleanups.
Follow-up works can drop diff lines unless we find a good reason for
divergence.
