hwmon: (adm1266) Set `can_sleep` flag for GPIO chip
The adm1266 driver uses 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.
