According to the ASUS WMI spec., to enable resume on lid open should
use the device ID(0x00120032), but it doesn't work indeed.
After discussing with ASUS' BIOS engineer, they say wake on lid open
doesn't have a uniq device ID(0x00120032) in the BIOS. It shares the same
device ID with deep S3(0x00120031), and the deep S3(resume on lid open)
is disable by default.
It's reasonable to resume the system while opening the lid, so add it
in the asus-wmi driver and tested the code on ASUS X100CH and ASUS 1015CX.
