power: supply: max17042_battery: Add default platform_data fallback data
Some x86 machines use a max17047 fuel-gauge and x86 might be missing platform_data if not provided by SFI. This commit adds default platform_data as fallback option so that the driver can work on boards where no platform_data is provided. Since not all boards have a thermistor hooked up, set temp_min to 0 and change the health checks from temp <= temp_min to temp < temp_min to not trigger on such boards (where temp reads 0).
