This patch passes the correct flag to vboot to enable SIMD crypto
acceleration on arm64 devices. This uses a core part of the ISA and
should thus be supported on all arm64 SoCs -- so we normally always
want it enabled, but there should still be a Kconfig in case a SoC wants
to use the hwcrypto interface for its own (off-CPU) crypto acceleration
engine instead. (You could also disable it to save a small amount of
code size at the cost of speed, if necessary.)
