It's afaik only for suspend/resume handling (E.G. low power).

SoC specific packages like this should depend on BR2_arm to not clutter
menuconfig for other archs.

I've added 'on am335x', otherwise it isn't clear that this is for
am335x.

I've also added the git location as upstream URL.

We normally give this the same name as what it get's installed to, so
I've prepended it with S93-.

And renamed here as well.

These lines are very long, so I've word wrapped them.

Committed to next with these changes, thanks.
