linux: update ngene/octopus

I have done some stupid (sysfs related) things to ddbridge
in order to make it compile with 3.17. as I dont have the
hardware, and there were no volunteers to test it, it was not
tested at all.

now it's fixed upstream

this should hopefuly fix #3646

@sraue could you please make a build based on 5.0 branch + this PR and upload to snapshots/test so @mglae can test it? I cant build oe5/master right now.. thanks.
