Subject: [PATCH v2 4/4] arm64: dts: exynos: gs101: add
 dm-verity-device-corrupted syscon-reboot-mode

On gs101, the boot mode is stored both in a syscon register, and in
nvmem.

Add the dm-verity-device-corrupted reboot mode to the syscon-reboot-
based boot mode as well, as both (nvmem & syscon) modes should be in
sync.
