[PATCH] config/arm: drop crypto extension from armv8.4-a build

[Shani Peretz <shperetz@nvidia.com>]

Remove the crypto march extension added by commit 6e6cc1dc3548
("config/arm: support crypto with Cortex-A78AE"). The extension
was added under the incorrect assumption that missing crypto ISA
caused an infinite loop, the actual cause was a GCC scheduling
issue with -mcpu=cortex-a78ae. This was avoided by switching to
-march=armv8.4-a in the same commit.

The extension is unnecessary and causes build failures on
toolchains without AES support. The -march=armv8.4-a build
without -mcpu is intentionally kept to avoid the scheduling issue.
