Bump minimum CMake version

Compatibility with versions <3.10 is going away.
As it happens, we're not using any CMake features that have changed
between 3.7 and 3.16, so bump the lowest version to 3.16.

Also remove the minimum version statement from the platform config
files --- they're all very simple files that are version independent;
and the version is checked elsewhere anyway.

Also, Fix style issue

A commit to fix style to make the PR go through.
