crypto: talitos - add support for sha224
SEC h/w versions 2.1 and above support sha224 via explicit instruction.
Performing sha224 ahashes on earlier versions is still possible because
they support sha256 (sha224 is sha256 with different initial constants
and a different truncation length). We do this by overriding hardware
context self-initialization, and perform it manually in s/w instead.
Thanks to Lee for his fixes for correct execution on actual sec2.0 h/w.
