crypto: stm32 - Support for STM32 HASH module

Browse source 
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.
