Add a new driver, qat_6xxx, to support QAT GEN6 devices. QAT GEN6 devices are a follow-on generation of GEN4 devices and differently from the previous generation, they can support all three services (symmetric, asymmetric, and data compression) concurrently. In order to have the qat_6xxx driver to reuse some of the GEN4 logic, a new abstraction layer has been introduced to bridge the two implementations. This allows to avoid code duplication and to keep the qat_6xxx driver isolated from the GEN4 logic. This approach has been used for the PF to VF logic and the HW CSR access logic.
