ACPI: asus_acpi: handle internal Bluetooth / support W5A
This patch creates a new file named "bluetooth" under /proc/acpi/asus/. This file controls both the internal Bluetooth adapter's presence on the USB bus and the associated LED. echo 1 > /proc/acpi/asus/bluetooth to enable, 0 to disable. Additionally, the patch add support for Asus W5A, the first model that uses this feature. Patch originally by Fernando A. P. Gomes.
