S3 wakeup requires waking vector in FACS table, which is typically set
by OS. This patchset enables FACS table support and allows setting
waking vector in "Hardware-reduced ACPI support only" builds
(CONFIG_ACPI_REDUCED_HARDWARE_ONLY=y).

v1->v2:
* Not removing acpi_hw_set_firmware_waking_vector() declaration in
  hwxfsleep.c
* Change was merged in ACPICA project, add links to it.
