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).

Link: https://github.com/acpica/acpica/commit/ee53ed6b5452612bb44af542b68d605f8b2b1104

v2->v3:
* Remove extra code style changes to align with original ACPICA commit.
v1->v2:
* Not removing acpi_hw_set_firmware_waking_vector() declaration in
  hwxfsleep.c
* Change was merged in ACPICA project, add links to it.

Jiaqing Zhao (2):
  ACPICA: Detect FACS in reduced hardware build
  ACPICA: Allow setting waking vector on reduced hardware platforms
