[PATCH 03/13] rockchip: rk3308: Enable ARMv8 crypto and FIT checksum validation

[Jonas Karlman]

The RK3308 SoC support ARMv8 Cryptography Extensions and use of the
ARMv8 crypto extensions help speed up FIT checksum validation in SPL.

Imply ARMV8_SET_SMPEN and ARMV8_CRYPTO to take advantage of the crypto
extensions for SHA256 when validating checksum of FIT images.

Imply SPL_FIT_SIGNATURE and LEGACY_IMAGE_FORMAT to enable FIT checksum
validation on all RK3308 boards.

Also disable CONFIG_SPL_RAW_IMAGE_SUPPORT in board defconfigs to ensure
SPL does not try to jump to code that failed checksum validation.
