soc/intel: drop Kconfig `PM_ACPI_TIMER_OPTIONAL`
Technically, it's not depending on the hardware but on the software
(OS/payload), if the PM Timer is optional. OSes with ACPI >= 5.0A
support disabling of the PM Timer, when the respective FADT flag is
unset. Thus, drop this guard.
For platforms without hardware PM Timer (Apollo Lake, Gemini Lake) the
Kconfig `USE_PM_ACPI_TIMER` depends on `!NO_PM_ACPI_TIMER`.
As of this change, new platforms must either implement code for
disabling the hardware PM timer or select `NO_PM_ACPI_TIMER` if no such
is present.
