Subject: [PATCH v5 04/23] Documentation: ACPI: move linuxized-acpica.txt to driver-api/acpi and convert to reST
This converts the plain text documentation to reStructuredText format and
add it to Sphinx TOC tree. No essential content change.

+Abstract
+========
This document describes the ACPICA project and the relationship between
ACPICA and Linux. It also describes how ACPICA code in drivers/acpi/acpica,
include/acpi and tools/power/acpi is automatically updated to follow the
upstream.

-1. ACPICA Project
-
- The ACPI Component Architecture (ACPICA) project provides an operating
- system (OS)-independent reference implementation of the Advanced
- Configuration and Power Interface Specification (ACPI). It has been
- adapted by various host OSes. By directly integrating ACPICA, Linux can
- also benefit from the application experiences of ACPICA from other host
- OSes.

- Ideally, all of the ACPICA commits should be converted into Linux patches
- automatically without manual modifications, the "linux / master" tree should
- contain the ACPICA code that exactly corresponds to the ACPICA code
