Corentin Labbe 7a70d9a1cf crypto: xilinx: prevent probing on non-xilinx hardware
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.
