This tells me nothing about what this patch does.

Neither does this.

And this sound like it should be a separate patch.

*However* when I look at the code, this does look like a single
change. And what is descibed as point 3 is the actual change in the patch.
Moreover, this patch addresses a historic horror, in that SVR_LX2160A
was defined both in the platform header and in the SoC header (which
I'm not saying you had necessarily noticed, but I am suggesting it is
added to the message).

If I wrote this commit message, I would start with a slightly tweaked
subject line:

Platform/NXP: Make SoC version log in ConfigurationManager generic

(CM is not a recognised abbreviation, so should be printed expanded)

As for the body, I would say something like:

This patch replaces the logic in ConfigurationManager to print
platform name based on platform ID with a simple #define.
This also removes a duplication of the SVR_LX2160A definition between
SoC and platform headers.

No comments on the code itself.
