Subject: [PATCH V3 0/4] crypto: Add Xilinx ZynqMP SHA3 driver support

This patch set does the following:
  - Updates the Makefile for xilinx subdirectory
  - Adds communication layer support for sha_hash in zynqmp.c
  - Adds Xilinx ZynqMP driver for SHA3 Algorithm
  - Updates the list of MAINTAINERS

Following tests have been done for the driver:
 - Enabled kernel self tests and extra run-time crypto self tests
 - Tested SHA hash computation for different sizes of data using
   userspace application
 - Tested SHA hash computation using multiple updates of data using
   userspace application
 - Tested parallel hash computation
 - Tested using the tcrypt module

V3 changes:
Added details of tests in cover letter
Added SOB for previous poster of RFC patch
Removed module_platform_driver in 3/4
Used memzero_explicit instead of memset in 3/4

V2 changes:
- Removed dependency on COMPILE_TEST in 3/4
- Rebased this patchset on latest Cryptodev-2.6 tree which fixed
below kernel robot warning
   In file included from ./arch/s390/include/generated/asm/cacheflush.h:1,
                    from drivers/crypto/xilinx/zynqmp-sha.c:6:
include/asm-generic/cacheflush.h:53:46: warning: 'struct folio' declared
inside parameter list will not be visible outside of this definition
or declaration
      53 | static inline void flush_dcache_folio(struct folio *folio) { }
         |
- Included linux/cacheflush.h instead of asm/cacheflush.h in 3/4
 
V1 changes:
- Converted RFC patch to PATCH
- Updated zynqmp-sha driver so that it can be self discovered 
- Removed patch 3/6 and 4/6 as they added support for device tree
- Substituted hw with hardware in drivers/crypto/Kconfig
