[Vivid][SRU][Pull-Request] add NX 842 hw compression patches

[Chris J Arges]

BugLink: http://bugs.launchpad.net/bugs/1454687

This patchset adds PowerPC NX crypto coprocessor support.
All of these patches have landed in at least 4.2-rc1, so presumably Wily
will get these when we rebase. This SRU is for landing these into v3.19 as well.

I've done a build test of this patch set.
