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.
