vendorcode/amd/agesa/f16kb: Enable support for AM1 socket

Adds option FORCE_AM1_SOCKET_SUPPORT to disable
package type mismatch check between cpu and northbridge.
Default agesa for kabini doesn't know about AM1 socket
so it returns FALSE, that stops memory config code.
With this hack current agesa version supports the AM1 socket.
