driver-core: Add attribute argument to class_attribute show/store
Passing the attribute to the low level IO functions allows all kinds
of cleanups, by sharing low level IO code without requiring
an own function for every piece of data.
Also drivers can extend the attributes with own data fields
and use that in the low level function.
This makes the class attributes the same as sysdev_class attributes
and plain attributes.
This will allow further cleanups in drivers.
Full tree sweep converting all users.
