From: Jonathan Cameron <Jonathan.Cameron@huawei.com>
Found whilst testing a series for the linux kernel that actually
bothers to check if enabled is set. 0xB is the option used
for vast majority of DSDT entries in QEMU.
It is a little odd for a device that doesn't really exist and
is simply a hook to tell the OS there is a CEDT table but 0xB
seems a reasonable choice and avoids need to special case
this device in the OS.
Means:
* Device present.
* Device enabled and decoding it's resources.
* Not shown in UI
* Functioning properly
* No battery (on this device!)
