Restrict user Set Access to certain attributes

Currently, we allow the host application to set a lot of attributes which in fact are completely controlled internally by the stack, e.g. the MAC address attribute of the EtherNetLink object whcih can be set via dedicated Hilscher services. A set into the attribute directory by the user has no effect, the attribute value is only set internally by the stack/object.

Please check the list of attributes and remove application set access for all attributes which are completely controlled internally by the stack.

This may need adaption of the host example code and test framework code
