Add two new properties for setting thte L3 power control register. Two
new properties are added:
arm,dynamic-clk-gating
arm,standby-mode
iMX6 sets both these, add the properties there.

I assume you want to squash this with patch 68/75? Or you are still
debating whether we want to do this or not? Given that it is r3px
only, that should greatly reduce any chance of breakage to newer
platforms.

I will eventually - I've kept it separate for the time being to give
more options. Let's see how people get on with it - it'll be running
through Olof's builder later today, and there's some other people
wanting to take it for a spin.

A while back I suggested altering those bits, but that was turned down:
https://lkml.org/lkml/2013/3/1/350
Are there any numbers available on how enabling these features impacts
the system? I'm a little bit concerned of always enabling them
unconditionally, in case it increases latency for some use cases. I
think I'd prefer the DT approach, unless the impact is reported to be
negligible - which it likely is, I guess.
Thanks,
Sören
