Armin Wolf 2bd1870a67
platform/x86: dell-ddv: Expose the battery health to userspace 
The health of a given battery is exposed over the Dell DDV WMI
interface using the "BatteryManufactureAceess" WMI method. The
resulting data contains, among other data, the health status of
the battery.

Expose this value to userspace using the power supply extension
interface.

Tested on a Dell Inspiron 3505.
