Subject: [PATCH] ARM: dts: trats2: add syscon-reboot-mode

Add syscon-reboot-mode dt node to support reboot mode. Trats2 uses
INFORM3 register with offset 0x80c not like odroid families.
In trats2's case, when we released the tizen-2.X with linux-3.10
kernel, it had used the INFORM3 register. That's why trats2 uses
the INFORM3 register for reboot-mode.
