From: "Steven J. Hill" Subject: [PATCH v2] MIPS: Octeon: mark GPIO controller node not populated after IRQ init.

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.
