Introduce ETH_SANDBOX_LWIP which enables a mock driver similar to ETH_SANDOX but without the dependencies on the legacy network stack (NET) so that it may be enabled when the lwIP stack (NET_LWIP) is introduced. The driver does nothing at this stage but its presence will allow dm_test_iommu_noiommu [1] to pass.
