Add node for fuel gauge present in Maxim 77693 PMIC. This allows control over battery charging state on Trats2 board. The fuel gauge is compatible with max17042 battery driver (Maxim 17042/17047/17050). Although datasheet rev 2.2 for MAX77693 describes fuel gauge as Maxim 17042-like, the chip on Trats2 board identifies itself as Maxim 17047-like.
