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.
