For some reason, the Microsoft Surface Go 3 uses the standard ACPI interface for battery information, but does not use the standard PNP0C0A HID. Instead it uses MSHW0146 as identifier. Add that ID to the driver as this seems to work well. Additionally, the power state is not updated immediately after the AC has been (un-)plugged, so add the respective quirk for that.
