Julius Werner d96ca24652 cbfs/vboot: Adapt to new vb2_digest API
CL:3825558 changes all vb2_digest and vb2_hash functions to take a new
hwcrypto_allowed argument, to potentially let them try to call the
vb2ex_hwcrypto API for hash calculation. This change will open hardware
crypto acceleration up to all hash calculations in coreboot (most
notably CBFS verification). As part of this change, the
vb2_digest_buffer() function has been removed, so replace existing
instances in coreboot with the newer vb2_hash_calculate() API.

Due to the circular dependency of these changes with vboot, this patch
also needs to update the vboot submodule:

Updating from commit id 18cb85b5:
    2load_kernel.c: Expose load kernel as vb2_api

to commit id b827ddb9:
    tests: Ensure auxfw sync runs after EC sync

This brings in 15 new commits.

Julius Werner 4bfbabdb54 cbfstool: Support CONFIG_CBFS_VERIFICATION and metadata hash anchor
This patch adds support for the new CONFIG_CBFS_VERIFICATION feature to
cbfstool. When CBFS verification is enabled, cbfstool must automatically
add a hash attribute to every CBFS file it adds (with a handful of
exceptions like bootblock and "header" pseudofiles that are never read
by coreboot code itself). It must also automatically update the metadata
hash that is embedded in the bootblock code. It will automatically find
the metadata hash by scanning the bootblock for its magic number and use
its presence to auto-detect whether CBFS verification is enabled for an
image (and which hash algorithm to use).
