Rename {CPU|NB|SB}/amd/*_wrapper folders
This change renames the cpu/amd/agesa_wrapper, northbridge/
amd/agesa_wrapper, and southbridge/amd/cimx_wrapper folders
to {cpu|NB}/amd/agesa and {SB}/amd/agesa to shorten and
simplify the folder names.
There is also a fix to vendorcode/amd/agesa/lib/amdlib.c to
append "ull" to a trio of 64-bit hexadecimal constants to
allow abuild to run successfully.
