gpu/stub: fix acpi_video build error, fix stub kconfig dependencies

The comments under "config STUB_POULSBO" are close to correct,
but they are not being followed.  This patch updates them to reflect
the requirements for THERMAL.

This build error is caused by STUB_POULSBO selecting ACPI_VIDEO
when ACPI_VIDEO's config requirements are not met.

  ERROR: "thermal_cooling_device_register" [drivers/acpi/video.ko] undefined!
  ERROR: "thermal_cooling_device_unregister" [drivers/acpi/video.ko] undefined!
