soc/intel: move disabling of PM Timer to SoC PMC code
Move disabling of PM Timer to SoC PMC code.
The original reason for placing that in `finalize` [1] was FSP hanging
due to use of the PM timer without enabling timer emulation first in
coreboot, which was added later [2].
[1] commit 6c1bf27dae (intel/skylake: disable ACPI PM Timer to enable
XTAL OSC shutdown)
[2] commit f004f66ca7 (soc/intel/skylake: Enable ACPI PM timer emulation
on all CPUs)
