create drivers/platform/x86/ from drivers/misc/

Move x86 platform specific drivers from drivers/misc/
to a new home under drivers/platform/x86/.

The community has been maintaining x86 vendor-specific
platform specific drivers under /drivers/misc/ for a few years.
The oldest ones started life under drivers/acpi.
They moved out of drivers/acpi/ because they don't actually
implement the ACPI specification, but either simply
use ACPI, or implement vendor-specific ACPI extensions.

In the future we anticipate...
drivers/misc/ will go away.
other architectures will create drivers/platform/<arch>

- * msi-laptop.c - MSI S270 laptop support. This laptop is sold under
- * various brands, including "Cytron/TCM/Medion/Tchibo MD96100".
- *
- * Driver also supports S271, S420 models.
- *
- * This driver exports a few files in /sys/devices/platform/msi-laptop-pf/:
- *
- *   lcd_level - Screen brightness: contains a single integer in the
- *   range 0..8. (rw)
- *
- *   auto_brightness - Enable automatic brightness control: contains
- *   either 0 or 1. If set to 1 the hardware adjusts the screen
- *   brightness automatically when the power cord is
- *   plugged/unplugged. (rw)
- *
- *   wlan - WLAN subsystem enabled: contains either 0 or 1. (ro)
- *
- *   bluetooth - Bluetooth subsystem enabled: contains either 0 or 1
- *   Please note that this file is constantly 0 if no Bluetooth
- *   hardware is available. (ro)
- *
- * In addition to these platform device attributes the driver
- * registers itself in the Linux backlight control subsystem and is
- * available to userspace under /sys/class/backlight/msi-laptop-bl/.
- *
- * This driver might work on other laptops produced by MSI. If you
- * want to try it you can pass force=1 as argument to the module which
- * will force it to load even when the DMI data doesn't identify the
- * laptop as MSI S270. YMMV.
