[00/11] crypto: caam - add DPAA2 (DPSECI) driver

Hi,

This patch set adds the CAAM crypto engine driver for DPAA2
(Data Path Acceleration Architecture v2) found on ARMv8-based SoCs
like LS1088A, LS2088A, LX2160A.

Previously sent RFC can be found here:
https://www.mail-archive.com/[e-mail]/msg27290.html

Driver consists of:
-DPSECI (Data Path SEC Interface) backend - low-level API that allows
to manage DPSECI devices (DPAA2 objects) that sit on
the Management Complex (MC) fsl-mc bus
-algorithms frontend - AEAD, skcipher and ahash algorithms implementation

Patches 1-4 are fsl-mc bus and DPIO dependencies.
Stuart, Laurentiu, Leo, Roy, please review the patches and let me know
if you have anything against going with them through the cryptodev tree.

Patches 5-10 are the core of the patch set, adding the driver.
For symmetric encryption the new skcipher interface is used.

Patch 11 enables driver on arm64. It will be built only if dependency
on DPIO (CONFIG_FSL_MC_DPIO) is satisfied.

Note: multiple modprobe/rmmod won't work without the following patches
[5/7,v7] bus/fsl-mc: support dma configure for devices on fsl-mc bus
https://patchwork.kernel.org/patch/10594179
[7/7,v7] arm64: dts: ls208xa: comply with the iommu map binding for fsl_mc
https://patchwork.kernel.org/patch/10594171
(for LS1088A a similar DT update is needed)

Thanks,
Horia
