[RFC PATCH V3 0/4] Add Xilinx's ZynqMP SHA3 driver support

[Kalyani Akula]

This patch set adds support for
- dt-binding docs for Xilinx ZynqMP SHA3 driver
- Adds communication layer support for sha_hash in zynqmp.c
- Adds Xilinx ZynqMP driver for SHA3 Algorithm
- Adds device tree node for ZynqMP SHA3 driver

V3 Changes :
- Removed zynqmp_sha_import and export APIs.The reason as follows
The user space code does an accept on an already accepted FD
when we create AF_ALG socket and call accept on it,
it calls af_alg_accept and not hash_accept.
import and export APIs are called from hash_accept.
The flow is as below
accept--> af_alg_accept-->hash_accept_parent-->hash_accept_parent_nokey
for hash salg_type.

V2 Changes :
- Added new patch (2/4) for sha_hash zynqmp API support
- Incorporated code review comments from v1 patch series. Discussed below:
