......................................................................

vboot: Add VBOOT_ARMV8_CE_SHA256_ACCELERATION config

Add Kconfig option for VBOOT_ARMV8_CE_SHA256_ACCELERATION, which will
use ARMv8 Crypto Extension for SHA256[1] instead of software
implementation.

This will speed up firmware verification in verstage.
