lib: polynomial: move to math/ subfolder

Patch series "lib: polynomial: Move to math/ and clean up", v2.

While removing Baikal SoC and platform code pieces I found that this code
belongs to lib/math/ rather than generic lib/. Hence the move and
followed up cleanups.


This patch (of 3):

The algorithm behind polynomial belongs to our collection of math
equations and expressions handling. Move it to math/ subfolder where
others of the kind are located.
