crypto: sha256 - Remove sha256/224_init code duplication
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.
