crypto: sha256 - Remove sha256/224_init code duplication

Browse Source 
lib/crypto/sha256.c and include/crypto/sha256_base.h define
99% identical functions to init a sha256_state struct for sha224 or
sha256 use.

This commit moves the functions from lib/crypto/sha256.c to
include/crypto/sha.h (making them static inline) and makes the
sha224/256_base_init static inline functions from
include/crypto/sha256_base.h wrappers around the now also
static inline include/crypto/sha.h functions.
