ARM cortex-a78ae configuration (part number 0xd42) is being built
without the necessary crypto extensions. This results in infinite
loops in the crypto performance tests applications because the
hardware crypto features are not properly enabled.
This fix enables the crypto extension in the mcpu definition.
Fixes: c02c01dbf907 ("config/arm: prefer strict use of -mcpu if supported")
