cpu/amd/agesa/Kconfig: Select LAPIC_MONOTONIC_TIMER

Thanks to Aaron Durbin coreboot provides monotonic timers. Select
    the LAPIC monotonic timer for the AMD AGESA CPUs.

The following is an excerpt from serial log of the ASRock E350M1.

$ grep usec seriallog-20130502_100902.log

        01.088: PNP: 002e.b init 30144 usecs
        01.088: PCI: 03:00.0 init 1663 usecs

So the graphics device needs around 100 ms for being initialized.

The full serial log is in the Gerrit comments.
