[ Upstream commit a5bb73b3f5db1a4e91402ad132b59b13d2651ed9 ]
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.
Fixes: d98dfad35c38 ("hwmon: (pmbus/adm1266) Add support for GPIOs")
