ACPI: move wmi, asus_acpi, toshiba_acpi to drivers/platform/x86

These are platform specific drivers that happen to use ACPI,
while drivers/acpi/ is for code that implements ACPI itself.

-	  This driver adds support for the ACPI-WMI (Windows Management
-	  Instrumentation) mapper device (PNP0C14) found on some systems.
-
-	  ACPI-WMI is a proprietary extension to ACPI to expose parts of the
-	  ACPI firmware to userspace - this is done through various vendor
-	  defined methods and data blocks in a PNP0C14 device, which are then
-	  made available for userspace to call.
-
-	  The implementation of this in Linux currently only exposes this to
-	  other kernel space drivers.
-
-	  This driver is a required dependency to build the firmware specific
-	  drivers needed on many machines, including Acer and HP laptops.
-
-	  It is safe to enable this driver even if your DSDT doesn't define
-	  any ACPI-WMI devices.

-        ---help---
-          This driver provides support for extra features of ACPI-compatible
-          ASUS laptops. As some of Medion laptops are made by ASUS, it may also
-          support some Medion laptops (such as 9675 for example).  It makes all
-          the extra buttons generate standard ACPI events that go through
-          /proc/acpi/events, and (on some models) adds support for changing the
-          display brightness and output, switching the LCD backlight on and off,
-          and most importantly, allows you to blink those fancy LEDs intended
-          for reporting mail and wireless status.
-
-	  Note: display switching code is currently considered EXPERIMENTAL,
-	  toying with these values may even lock your machine.
-
-          All settings are changed via /proc/acpi/asus directory entries. Owner
-          and group for these entries can be set with asus_uid and asus_gid
-          parameters.
-
-          More information and a userspace daemon for handling the extra buttons
-          at <http://sourceforge.net/projects/acpi4asus/>.
-
-          If you have an ACPI-compatible ASUS laptop, say Y or M here. This
-          driver is still under development, so if your laptop is unsupported or
-          something works not quite as expected, please use the mailing list
-          available on the above page (acpi4asus-user@lists.sourceforge.net).
-
-	  NOTE: This driver is deprecated and will probably be removed soon,
-	  use asus-laptop instead.

-	select NET
-	select RFKILL
-	select BACKLIGHT_CLASS_DEVICE
-	---help---
-	  This driver adds support for access to certain system settings
-	  on "legacy free" Toshiba laptops.  These laptops can be recognized by
-	  their lack of a BIOS setup menu and APM support.
-
-	  On these machines, all system configuration is handled through the
-	  ACPI.  This driver is required for access to controls not covered
-	  by the general ACPI drivers, such as LCD brightness, video output,
-	  etc.
-
-	  This driver differs from the non-ACPI Toshiba laptop driver (located
-	  under "Processor type and features") in several aspects.
-	  Configuration is accessed by reading and writing text files in the
-	  /proc tree instead of by program interface to /dev.  Furthermore, no
-	  power management functions are exposed, as those are handled by the
-	  general ACPI drivers.
-
-	  More information about this driver is available at
-	  <http://memebeam.org/toys/ToshibaAcpiDriver>.
-
-	  If you have a legacy free Toshiba laptop (such as the Libretto L1
-	  series), say Y.
