NAK.
Please do not enforce such a policy on all your users. Let them
decide if they want this, or not.

Do we need a new custom command for this? Either allow setting by
environment variable only ("cpuclk" is already used by a number of
systems), or use a common command name ("chip_config" was chosen for
this after some discussion a while ago).
Also, is no further checking needed? Can I set arbitrary frequencies,
like 307 for CPU and 277 for DDR?

Incorrect multiline comment once more.

Argh. Please do not do this.

Ditto.

I don't like such board-specific code in this common file.
