soc/intel/common: add Kconfig to enable/disable the ACPI PM timer

Currently, the ACPI PM timer state gets set in devicetree by the option
PmTimerDisabled. However, it is not board design dependent. Thus, add a
user-selectable Kconfig option.

Also, make the TCO SMI option depend on ACPI PM timer, since it won't
work without it.

The Kconfig option depends on CTC (Common Timer Copy), which the SoC has
to support to do PM ACPI timer emulation.

This new Kconfig gets used in the follow-up commits of this series.

Note: On Apollolake USE_PM_ACPI_TIMER gets selected statically to avoid
confing the user in menuconfig, where the option is shown due to using
the common code for PM Timer emulation. Currently, there is no FSP
option and no coreboot code to disable the PM ACPI Timer and it is
unknown if that is desireable on that platform.
