Patrick Rudolph b9959e279c cpu/intel/model_206ax: Use tsc monotonic timer
Switch from lapic to tsc.

Allows timestamps to be used in coreboot, as there's a reference
clock available to calculate correct time units.

Clean Kconfig, remove duplicated lapic code and include tsc dir for
LGA1155 boards.

Tested on Lenovo T430.
