Eliminate possible sha_transform unaligned accesses to data by copying
data to an aligned __u32 array if necessary.

This is wrong. Not only does it double the stack space, when I tried
it for git it just made things slower. So don't do it.

Maybe the aligned copy should be in an
#ifndef CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS block.

Maybe Mandeep could test aligned/unaligned speeds
for his board?
