AMD AGESA: Add missing breaks to switch statement in one file

This is the same patch as an earlier one applied to family 15 [1].

Static analysis often flags case statements that do not include
a terminating "break;" statement. Eclipse's CODAN is an example
of this.  This changelist modifies amdlib.c to terminate
case statements with "break;".
