[PATCH v2 0/2] PBL: add support for optimized sha256

[Sascha Hauer]

When chainloading a full barebox from the PBL we have to verify the
loaded image with sha256. This can take some time for bigger image, so
add support for optimized implementations and ad the ARM64 Crypto
Extensions as a first implementation
