healthd: don't report fake data for battery-less devices
If the kernel does not implement a power_supply class device of type battery, do not report fake data, instead report the following by default: * batteryPresent = false (instead of true), * charging status = unknown (instead of charging), * capacity = 0 (instead of 100%), * health = unknown (instead of good), * AC charger online not modified (instead of forcing true) If no charger and no battery devices are supplied by the kernel, the AC charger online property will no longer be forced to true. Devices that are always plugged into AC power should either implement a power_supply class charger device or implement a Health HAL that sets properties appropriately. Bug: 34507420 Test: manual: gce_x6_phone (no battery or charger), boots and stays booted, inspect properties Merged-In: I14cb3b685e8130428e417e7d08c4246f7415210a Change-Id: I64bd4431af10f3d232f36fcf8d356b6d88b08013
