The intel-int3496.txt file is a documentation for an ACPI driver.
There's no reason to keep it on a separate directory.
So, instead of keeping it on some random location, move it
to a sub-directory inside the ACPI documentation dir.
For now, keep it with .txt extension, in order to avoid
Sphinx build noise. A later patch should change it to .rst
and movin it to be together with other acpi docs.
