This should be disabled for devices running on battery since
it can draw much power. Further, it must be disabled, if S0ix
is enabled.
Disabling this option also stops the hardware TCO timer and makes
the TCO watchdog unavailable.
Note: On platforms without uCode PM Timer emulation, legacy OSes
or payloads with ACPI version < 5.0A might not work without
PM ACPI timer.
(Legacy) software requiring `TMR_STS` (for timer overflow
interrupts) will not work with this option disabled.
