Subject: [PATCH v3 0/2] S3 wakeup support for hardware reduced model

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.

  ACPICA: Detect FACS in reduced hardware build
  ACPICA: Allow setting waking vector on reduced hardware platforms
