Picking up where Chris left off (I chatted with him privately
beforehead), this series adds support for i.MX8MQ to CAAM driver. Just
like [v1], this series is i.MX8MQ only.

Feedback is welcome!

Changes since [v5]:

  - Hunk replacing sizeof(*jrp->inpring) to SIZEOF_JR_INPENTRY in
    "crypto: caam - don't hardcode inpentry size", lost in [v5], is

  - Collected Tested-by from Iuliana

Changes since [v4]:

  - Fixed missing sentinel element in "crypto: caam - simplfy clock
  - Squashed all of the devers related patches into a single one and
    converted IRQ allocation to use devres while at it

  - Added "crypto: caam - request JR IRQ as the last step" as

Changes since [v3]:

  - Patchset changed to select DMA size at runtime in order to enable
    support for both i.MX8MQ and Layerscape at the same time. I only
    tested the patches on i.MX6,7 and 8MQ, since I don't have access
    to any of the Layerscape HW. Any help in that regard would be

  - Bulk clocks and their number are now stored as a part of struct
    caam_drv_private to simplify allocation and cleanup code (no
    special context needed)
  - Renamed 'soc_attr' -> 'imx_soc_match' for clarity

Changes since [v2]:

  - Dropped "crypto: caam - do not initialise clocks on the i.MX8" and
    replaced it with "crypto: caam - simplfy clock initialization" and 
    "crypto: caam - add clock entry for i.MX8MQ"

Changes since [v1]

  - Series reworked to continue using register based interface for
    queueing RNG initialization job, dropping "crypto: caam - use job
    ring for RNG instantiation instead of DECO"

  - Added a patch to share DMA mask selection code

  - Added missing Signed-off-by for authors of original NXP tree
    commits that this sereis is based on
