arm64: dts: exynos: add syscon reboot/reboot_mode support in ExynosAutov9

Browse source

Reboot of exynosautov9 SoC can be handled by setting the
bit(SWRESET_SYSTEM[1]) of SYSTEM_CONFIGURATION register(PMU + 0x3a00).
syscon-reboot-mode can be used to indicate the reboot mode for
bootloader. SYSIP_DAT0 register(PMU + 0x810) will not be cleared after
reboot so bootloader can enter the boot mode according to the value.
