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>

-          unlikely to need NVRAM polling in their latest BIOS versions.
-
-          NVRAM polling can detect at most the following keys: ThinkPad/Access

+          This support was made obsolete by the generic ACPI docking station
+          support (CONFIG_ACPI_DOCK).  It will allow locking and removing the
+          laptop from the docking station, but will not properly connect PCI

+          Allows the thinkpad_acpi driver to provide an interface to control
+          the various video output ports.
+
+          This feature often won't work well, depending on ThinkPad model,
+          display state, video output devices in use, whether there is a X
+          server running, phase of the moon, and the current mood of
+          Schroedinger's cat.  If you can use X.org's RandR to control
+          your ThinkPad's video output ports instead of this feature,
+          don't think twice: do it and say N here to save some memory.
+

+
+config THINKPAD_ACPI_HOTKEY_POLL
+        bool "Support NVRAM polling for hot keys"
+        depends on THINKPAD_ACPI
+        default y
+        ---help---
+          Some thinkpad models benefit from NVRAM polling to detect a few of
+          the hot key press events.  If you know your ThinkPad model does not
+          need to do NVRAM polling to support any of the hot keys you use,
+          unselecting this option will save about 1kB of memory.
+
+          ThinkPads T40 and newer, R52 and newer, and X31 and newer are
+          unlikely to need NVRAM polling in their latest BIOS versions.
+
+          NVRAM polling can detect at most the following keys: ThinkPad/Access
+          IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
+          Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
+
+          If you are not sure, say Y here.  The driver enables polling only if
+          it is strictly necessary to do so.
