soc/intel: transition full control over PM Timer from FSP to coreboot

Set `EnableTcoTimer=1` in order to keep FSP from
 1) enabling ACPI Timer emulation in uCode.
 2) disabling the PM ACPI Timer.

Both actions are now done in coreboot.

`EnableTcoTimer=1` makes FSP skip these steps in any possible case
including `SkipMpInit=0`, `SkipMpInit=1`, use of the MP PPI or FSP
Multiphase Init. This way full control is left to coreboot.
