Subject: ACPI: Clean up inclusions of ACPI header files

Replace direct inclusions of <acpi/acpi.h>, <acpi/acpi_bus.h> and
<acpi/acpi_drivers.h>, which are incorrect, with <linux/acpi.h>
inclusions and remove some inclusions of those files that aren't
necessary.

First of all, <acpi/acpi.h>, <acpi/acpi_bus.h> and <acpi/acpi_drivers.h>
should not be included directly from any files that are built for
CONFIG_ACPI unset, because that generally leads to build warnings about
undefined symbols in !CONFIG_ACPI builds.  For CONFIG_ACPI set,
<linux/acpi.h> includes those files and for CONFIG_ACPI unset it
provides stub ACPI symbols to be used in that case.

Second, there are ordering dependencies between those files that always
have to be met.  Namely, it is required that <acpi/acpi_bus.h> be included
prior to <acpi/acpi_drivers.h> so that the acpi_pci_root declarations the
latter depends on are always there.  And <acpi/acpi.h> which provides
basic ACPICA type declarations should always be included prior to any other
ACPI headers in CONFIG_ACPI builds.  That also is taken care of including
<linux/acpi.h> as appropriate.

Subject: ACPI / thermal: remove const from thermal_zone_device_ops declaration

The following commit introduced the requirement to not declare
thermal_zone_device_ops structs as const in order to allow
changing the .get_temp callback.

commit 4e5e4705bf69ea450f58fc709ac5888f321a9299
Author: Eduardo Valentin <eduardo.valentin@ti.com>
Date:   Wed Jul 3 15:35:39 2013 -0400

    thermal: introduce device tree parser

Modify acpi_thermal_zone_ops to follow the new requirement.
