ACPI / video: move video_extension.txt to Documentation/acpi

ACPI video driver is written according to ACPI spec, appendix B: Video
Extensions. So it better be put under the acpi directory instead of the
power directory. This patch moves the file there without any other
change.

+ACPI video extensions
+~~~~~~~~~~~~~~~~~~~~~
+
+This driver implement the ACPI Extensions For Display Adapters for
+integrated graphics devices on motherboard, as specified in ACPI 2.0
+Specification, Appendix B, allowing to perform some basic control like
+defining the video POST device, retrieving EDID information or to
+setup a video output, etc.  Note that this is an ref. implementation
+only.  It may or may not work for your integrated video device.
+
+Interfaces exposed to userland through /proc/acpi/video:
+
+VGA/info : display the supported video bus device capability like Video ROM, CRT/LCD/TV.
+VGA/ROM :  Used to get a copy of the display devices' ROM data (up to 4k).
+VGA/POST_info : Used to determine what options are implemented.
+VGA/POST : Used to get/set POST device.
+VGA/DOS : Used to get/set ownership of output switching:
+       Please refer ACPI spec B.4.1 _DOS
+VGA/CRT : CRT output
+VGA/LCD : LCD output
+VGA/TVO : TV output
+VGA/*/brightness : Used to get/set brightness of output device
