healthd: Set fixed battery level and temperature via properties
setprop persist.sys.battery.capacity 77
setprop persist.sys.battery.temperature 123
and reboot to cause a fixed battery level of 77% and temperature of 12.3C
to be reported to Android.
Typically used on power evaluation boards without batteries connected.
