    hwmon: (ltc2992) Set `can_sleep` flag for GPIO chip
    
    [ Upstream commit ab00709310eedcd8dae0df1f66d332f9bc64c99e ]
    
    The ltc2992 drivers uses a mutex and I2C bus access in its GPIO chip `set`
    and `get` implementation. This means these functions can sleep and the GPIO
    chip should set the `can_sleep` property to true.
    
    This will ensure that a warning is printed when trying to set or get the
    GPIO value from a context that potentially can't sleep.
