The crypto4xx SHA implementation keeps the hash state in the tfm
data structure. This breaks a fundamental requirement of ahash
implementations that they must be reentrant.
This patch disables the broken implementation.

This patch changes crypto4xx to use the new style ahash type.
In particular, we now use ahash_alg to define ahash algorithms
instead of crypto_alg.
This is achieved by introducing a union that encapsulates the
new type and the existing crypto_alg structure. They're told
apart through a u32 field containing the type value.

This patch makes crypto4xx use crypto_ahash_set_reqsize to avoid
accessing crypto_ahash directly.

This patch adds support for AMCC ppc4xx security device driver. This is the
initial release that includes the driver framework with AES and SHA1 algorithms
support.
The remaining algorithms will be released in the near future.
