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.
