powerpc: Add a powerpc implementation of SHA-1
This patch adds a crypto driver which provides a powerpc accelerated implementation of SHA-1, accelerated in that it is written in asm. Original patch by Paul, minor fixups for upstream by moi. Lightly tested on 64-bit with the test program here: http://michael.ellerman.id.au/files/junkcode/sha1test.c Seems to work, and is "not slower" than the generic version. Needs testing on 32-bit.
