crypto: stm32 - Support for STM32 HASH module

This module register a HASH module that support multiples algorithms: MD5, SHA1, SHA224, SHA256. It includes the support of HMAC hardware processing corresponding to the supported algorithms. DMA or IRQ mode are used depending on data length. Signed-off-by: Lionel Debieve <lionel.debieve@st.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
