[PATCH] ARM: dts: aspeed: rainier: Add N_MODE_VREF gpio

From: Adriana Kobylak <anoo at us.ibm.com>

The N_MODE_VREF gpio is designed to be used to notify the Onboard Chip
Controller how many power supplies the system should have (2 or 4). This
gpio is on a 9552, populate all the gpios on that chip for completeness.
