Ard Biesheuvel 7a689ebc67 ANDROID: crypto: lib/sha256 - add vendor hook for sha256() routine ...

Add a vendor hook that will allow the FIPS140 kernel module to override
the implementation of the sha256() library routine. The FIPS 140 version
is identical to the normal one, but its code and rodata will have been
integrity checked at module load time.
