MIPS: Octeon: mark GPIO controller node not populated after IRQ init.

We clear the OF_POPULATED flag for the GPIO controller node on Octeon processors. Otherwise, none of the devices hanging on the GPIO lines are probed. The 'gpio-leds' driver on OCTEON failed to probe in addition to other devices on Cavium 71xx and 78xx development boards.

Fixes 15cc2ed6dcf9 ("of/irq: Mark initialised interrupt controllers as populated")

Ralf, I think this patch should be still included in v4.8 final.

Thanks,
