[PATCH] DTC - validation by device_type

>>> +	CHECK_HAVE(net, "reg");
>>> +	CHECK_HAVE(net, "local-mac-address");
>>> +	CHECK_HAVE(net, "mac-address");
>>> +	CHECK_HAVE(net, "address-bits");

1) It's hard to see how any (physical) network device would
not have a "reg" property.  It is not required though.

2) "local-mac-address" is not a required property.

3) "mac-address" is only required for nodes that have been
opened before.

4) "address-bits" is not required (taken as 48 if absent).

Please see Annex A (look at the property names, and perhaps
at the "network" device type).  _Always_ look at Annex A!
It's normative.
