soc/amd/common: Move AGESA related source files

Move AGESA related source files in soc/amd/common under block directory.
Folder soc/amd/common/block subfolders should mimic soc/intel/common/block
subfolders (one subfolder per subject).

BUG=b:69262110
TEST=Build with no error gardenia and kahlee (no code change, just folder
reorg).
