Remove some properties in oic.r.devconf resource

Remove some properties in oic.r.devconf resource

Problem:
 Some of properties in oic.r.devconf resource has a duplicated meaning with
other existing resource's one like oic.wk.con and oic.wk.p. For OCF spec,
such a duplication should be avoided as possible.

Way to resolve:
All properties EXCEPT device name("dn") property are removed.
Later, some properties can be defined in oic.r.devconf with spec update.
