Export asus_wmi_evaluate_method() and related headers for use by other
drivers.
hid-asus is going to use this to avoid advertising that it has a keyboard
backlight when the keyboard backlight is controlled via WMI.
Signed-off-by: Daniel Drake <drake@xxxxxxxxxxxx>

Notes:
v2: instead of copying asus-wmi code into hid-asus, split it out like this
v3: add stub function for when asus-wmi is not built
