The zynqmp-sha driver is always loaded and register its algorithm even on
platform which do not have the proper hardware.
This lead to a stacktrace due to zynqmp-sha3-384 failing its crypto
self tests.
So check if hardware is present via the firmware API call get_version.
While at it, simplify the platform_driver by using module_platform_driver()
Furthermore the driver should depend on ZYNQMP_FIRMWARE since it cannot
work without it.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
