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.
