RDMA/bnxt_re: Support doorbells for app allocated QPs
App allocated QPs can use a separate doorbell for each QP.
This doorbell region can be passed through a new driver specific
DBR_HANDLE attribute, during QP creation. When this attribute
is set, associate the QP with the given doorbell region.
While the QP holds a reference to the dbr, the dbr itself
cannot be destroyed and is rejected with EBUSY error.
