crypto: sha256 - Make lib/crypto/sha256.c suitable for generic use
Before this commit lib/crypto/sha256.c has only been used in the s390 and
x86 purgatory code, make it suitable for generic use:
* Export interesting symbols
* Add -D__DISABLE_EXPORTS to CFLAGS_sha256.o for purgatory builds to
avoid the exports for the purgatory builds
* Add to lib/crypto/Makefile and crypto/Kconfig
