aspeed/hace: Support AST2600 HACE
The aspeed ast2600 accumulative mode is described in datasheet
ast2600v10.pdf section 25.6.4:
1. Allocating and initiating accumulative hash digest write buffer
with initial state.
* Since QEMU crypto/hash api doesn't provide the API to set initial
state of hash library, and the initial state is already set by
crypto library (gcrypt/glib/...), so skip this step.
2. Calculating accumulative hash digest.
(a) When receiving the last accumulative data, software need to add
padding message at the end of the accumulative data. Padding
message described in specific of MD5, SHA-1, SHA224, SHA256,
SHA512, SHA512/224, SHA512/256.
* Since the crypto library (gcrypt/glib) already pad the
padding message internally.
* This patch is to remove the padding message which fed byguest
machine driver.
