PATCH 1/1 staging: skein: Loadable Module Support

Adds loadable module support for Skein256, Skein512, and Skein1024
NOTE: skein1024_generic does not load, sending patch for feedback! I don't understand why skein256_generic and skein512_generic load no problem but skein1024_generic gives ERROR: Invalid argument from modprobe.
