arm64: dts: exynos: gs101: add syscon-poweroff and syscon-reboot nodes

Browse source

Reboot of gs101 SoC can be handled by setting the
bit(SWRESET_SYSTEM[1]) of SYSTEM_CONFIGURATION register(PMU + 0x3a00).

Poweroff of gs101 SoC can be handled by setting bit(DATA[8]) of
PAD_CTRL_PWR_HOLD register (PMU + 0x3e9c).

Tested using "reboot" and "poweroff -p" commands.
