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>

-
-	  ThinkPads T40 and newer, R52 and newer, and X31 and newer are
