bridge: mrp: Extend MRP netlink interface for configuring MRP interconnect

Browse Source 
This patch extends the existing MRP netlink interface with the following
attributes: IFLA_BRIDGE_MRP_IN_ROLE, IFLA_BRIDGE_MRP_IN_STATE and
IFLA_BRIDGE_MRP_START_IN_TEST. These attributes are similar with their
ring attributes but they apply to the interconnect port.
