bridge: mrp: Add 'enum br_mrp_hw_support' 



Add the enum br_mrp_hw_support that is used by the br_mrp_switchdev
functions to allow the SW to detect the cases where HW can't implement
the functionality or when SW is used as a backup.

/* This type is returned by br_mrp_switchdev functions that allow to have a SW

 * backup in case the HW can't implement completely the protocol.

 * BR_MRP_NONE - means the HW can't run at all the protocol, so the SW stops

 *               configuring the node anymore.

 * BR_MRP_SW - the HW can help the SW to run the protocol, by redirecting MRP

 *             frames to CPU.

 * BR_MRP_HW - the HW can implement completely the protocol.
