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")

Tested-by: Aaro Koskinen <redacted>Ralf, I think this patch should be still included in v4.8 final. Thanks, A.
