rk3288: Implement support for CRYPTO module and use it in vboot hashing

Hardware / Coreboot - Julius Werner [chromium.org] - 15 April 2015 09:45 UTC

This patch implements support for the CRYPTO module in RK3288 and ties it into the new vboot vb2ex_hwcrypto API. We only implement SHA256 for now, since the engine doesn't support SHA512 and it's very unlikely that we'll ever use SHA1 for anything again.

BRANCH=None BUG=chrome-os-partner:32987 TEST=Booted Pinky, confirmed that it uses the hardware crypto engine and that firmware body hashing time dropped to about 1.5ms (from over 70ms).
