[PATCH 00/31] crypto: qat - rework in preparation for qat_4xxx driver

[Giovanni Cabiddu <giovanni.cabiddu@intel.com>]

This set is an initial rework of the QAT driver in preparation for the
inclusion of the qat_4xxx driver (QAT GEN4).

Summary of changes:
  * IV update logic moved to software to remove allocation of the IV
    buffer in the data-path and allow for devices that are not capable
    of updating it when performing AES-CBC or AES-CTR.
  * Added logic to detect the presence of engines and accelerators via
    soft-straps and fuse registers.
  * Added infrastructure to support devices with an arbitrary number of
    rings per bank.
  * Introduced adf_gen2_hw_data.[c|h] that contain logic that is common
    between QAT GEN2 devices (c62x, c3xxx and dh895xcc).
  * Abstracted logic that configures iov threads.
  * Abstracted access to transport CSRs.
  * Abstracted, refactored and updated admin interface logic.
  * Abstracted and refactored arbiter logic.
  * Changed sequence on how arbitration is enabled on rings.
  * Added support for device capability detection.
  * Replaced hardcoded masks.
  * Changed logic in adf_sriov.c to allow for drivers that do not
    implement some of the functions of that module.
  * Refactored logic related to device configuration and instance
    creation.
  * Changed logic to allow for instances in different banks.
  * Extended accelerator mask.
