AMD Fam14 - Fix warnings

Added casts and a couple of #ifdefs to fix the warnings in the
vendorcode/amd/agesa/f14 codebase.  This will allow us to re-enable
'all warnings being treated as errors' in boards such as Persimmon
that are using this code.  That change will follow.

These are the warnings that are fixed by this patch:
