Logan Gunthorpe 6619bf9549 NTB: switchtec_ntb: Implement doorbell registers ... Pretty straightforward implementation of doorbell registers. The shift and mask were setup in an earlier patch and this just hooks up the appropriate portion of the IDB register as the local doorbells and the opposite portion of ODB as the peer doorbells. The DB mask is protected by a spinlock to avoid concurrent read-modify-write accesses.
