How does this improve the results?

config X86_INTEL_LPSS
	bool "Intel Low Power Subsystem Support"
	depends on X86 && ACPI && PCI

So the X86 dependency is already there. Does this happen with 
COMPILE_TEST set? If yes, maybe that's the part that needs to be 
changed? The addition of COMPILE_TEST here is quite recent and might 
need to be reverted.
