hwmon: (ltc2992) Set `can_sleep` flag for GPIO chip
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.
