x86/Voyager: remove power management Kconfig quirk

Voyager has this PM/ACPI Kconfig quirk:

 menu "Power management and ACPI options"
	depends on !X86_VOYAGER

Most of the PM features are auto-detect so they should be safe to run
on just about any hardware. (If not, those instances need fixing.)

In any case, if a kernel is built for Voyager, the power management
options can be disabled.
