vendorcode/amd/agesa/f14: Fix improper use of .data

AGESA has a lot of code in the .data section which is for initialized
data, that in fact should be .rodata. This adds the 'CONST' keyword
everywhere it is needed.

TEST: See in the .elf file (e.g. using readelf) that there is nothing in
.data section.
