hsr: introduce rx offload feature flags for HSR and PRP

This patch introduces the HSR/PRP rx offload flag to allow offload
of LRE rx side processing such as duplicate detect/drop, node_table,
etc to h/w. Lower level Ethernet drivers that support h/w with these
protocol handling list this feature in the feature flag of the
net_device.
