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.
