You also need to account for included Kconfigs, specifically:

drivers/platform/surface/aggregator/Kconfig.

This is redundant, you can drop that. ACPI_WMI already depends on ACPI.

As mentioned above, you're missing aggregator/Kconfig. All you need to
do is add "depends on ACPI" to SURFACE_AGGREGATOR in that file. Then you
can drop the "depends on ACPI" for anything that depends on that.

Same holds for the couple of options depending on SURFACE_AGGREGATOR
below.
