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:

Seems to work, and is "not slower" than the generic version.

Needs testing on 32-bit.
