cbfs: Add file data hashing for CONFIG_CBFS_VERIFICATION
This patch adds file data hashing for CONFIG_CBFS_VERIFICATION. With
this, all CBFS accesses using the new CBFS APIs (cbfs_load/_map/_alloc
and variants) will be fully verified when verification is enabled. (Note
that some use of legacy APIs remains and thus the CBFS_VERIFICATION
feature is not fully finished.)
