IB/core: Introduce driver QP type
Vendors can implement type of QPs that are not described in the InfiniBand specification. To still be able to use the IB/core layer services (e.g. user object management) without tainting this layer with driver proprietary logic, a new QP type is added - IB_QPT_DRIVER. This will be a general QP type that the core layer doesn't know about its true nature. When a command like create_qp() is passed to a hardware driver the extra data that is required is taken from the driver channel. Downstream patches from this series will use that QP type in the mlx5 driver.
