vendorcode/amd/agesa: unsigned enum is strictly positive 

The typedef'ed BIT_FIELD_NAME enum is type unsigned. The parameter
'FieldName' is decleared with type BIT_FIELD_NAME and thus the redudant
comparison of unsigned enum expression >= 0 is always true.

BIT_FIELD_NAME is declared in vendorcode/amd/agesa/f14/Proc/Mem/mm.h
