soc/intel: replace dt option PmTimerDisabled by Kconfig
Replace the dt option `PmTimerDisabled` with use of the Kconfig option
`USE_PM_ACPI_TIMER` for enabling/disabling the PM Timer.
A default value representing the prior devicetree value was added to the
boards system76/{lemp10,galp5,darp7}, so this change will not alter
behaviour.
