sha-2 encrypted password

[Roman Rakus]

Hi,
please take a look at http://csrc.nist.gov/groups/ST/hash/policy.html. 
MD5 is considered quite insecure nowadays, so use this patch, which adds 
support for SHA-2 encrypted passwords to yaboot.
I have tested it a bit. MD5, SHA-256 and SHA-512 worked well. Another 
change can be to add #ifdef USE_SHA2_PASSWORD.
