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.
