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.)
