platform/x86: drop deprecated asus_acpi driver

2012-03-20T16:02:18Z

asus_acpi only support old models, it has been deprecated since 2009 in favor of asus-laptop, it's not built by any (sane) distro, so it is time to say good bye. Thanks to Julien Lerouge and Karol Kozimor for the work they have done on it, I would never have wrote asus-laptop and other asus related drivers without asus_acpi.
