AMD Fam15tn boards: BiosCallOuts.c: Declare codec arrays as `static`

These arrays are declared as `static` for AMD SB800 based boards,
so do the same for this generation.

Rudolf Marek just changed `const CODEC_TBL_LIST` to `static const`
in [1]. Adapt all Fam15tn based boards (AMD Parmer, AMD Thatcher,
ASUS F2A85-M) to keep the differences between them small.
