hwmon: (sysfs) Allow drivers to register const attributes

Browse source

Switch to the __DEVICE_ATTR() macro which can handle callbacks taking
both const and non-const attribute structure arguments.
Allow the step-wise migration of the drivers.

Also use container_of_const() over container_of() to avoid casting away
the constness accidentally.
