vboot2: Implement new vb2ex_hwcrypto API
This patch aligns our verstage code to the new API addition in vboot2.
The hardware crypto functions are stubbed out by default and just
pretend that all algorithms are unsupported, causing vboot to fall back
to the normal software hashing code. These weak symbols can be
overridden by individual platform code to provide actual hardware
crypto engine support.

BUG=chrome-os-partner:32987
TEST=Booted Pinky, confirmed vboot falls back to software crypto.
