We clear the OF_POPULATED flag for the GPIO controller node, otherwise
the GPIO lines used by the MMC driver are never probed.
Please also mention that gpio-leds failed to probe.

I suspect that it is not just MMC that was broken by commit 15cc2ed6dcf9.
Can we get a real description of exactly which kernel facilities are
impacted? Is it all GPIO, or what?
For me it fixes gpio-leds breakage, so I think it's all GPIO. Referring
to MMC driver is not appropriate anyway as the OCTEON MMC is not yet
merged. :-)
