Implement new behavior for OEM parameter handling

For the behavior regarding the OEM parameters:

• serial number
• harder number
• hardware revision
• mac addresses

a new definition has been made. This new behavior shall be implemented:

• When setting a new configuration, the OEM parameters are validated in Device Data Provider
• When activating a new configuration from previously unconfigured state, all valid/active OEM parameters from Device Data Provider are applied, Overwritting any previously made settings, even configuration supplied values.

Also the Device Data Provider has been extended to support OEM values for some fields. These shall be taken into account if active.
