util: resource: Add preprocessing before updating attributes

There are resource information to be shared between attributes, so as
to support these resources this introduces prepare_update(), the new
driver operation called before update_resource_attrs() automatically.
In order to prevent updating each resource individually, removes
get_resource_attr_*_sync() functions and prohibits calling
update_resource_attr() soley.
