[Qemu-devel] [PATCH v1 06/15] android-console: Add missing hw_has_battery prop

[Greg Bellows]

Added the missing hw_has_battery property to the Goldfish batter state.  This
property indicates whether the device has a battery and controls whether some
power commands are available.

In the Android emulator this property is acquired from the AVD for the device.
For now, this is wired as always enabled.
