Current SBL supports container header verification. If the container
signature is BOOT, it will use HASH_USAGE_PUBKEY_OS. Otherwise, it
will use HASH_USAGE_PUBKEY_CONTAINER_DEF. This patch added OEM signed
container support. If a container signature between OEM0 to OEM7 is
found, it will be verified use HASH_USAGE_PUBKEY_OEM(x) where x is 0
to 7. To add an OEM public key hash, it can be done by updating
pub_key_list in GetKeyHashList() in file BoardConfig.py.
