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>

- * comapl-laptop.c - Compal laptop support.
- *
- * This driver exports a few files in /sys/devices/platform/compal-laptop/:
- *
- *   wlan - wlan subsystem state: contains 0 or 1 (rw)
- *
- *   bluetooth - Bluetooth subsystem state: contains 0 or 1 (rw)
- *
- *   raw - raw value taken from embedded controller register (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/compal-laptop/.
- *
- * This driver might work on other laptops produced by Compal. 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 FL9x.
