Modern device tree bindings are supposed to be created as YAML-files
in accordance with dt-schema. This commit replaces SYSCON reboot-mode
legacy bare text bindings with YAML file. As before the bindings file
states that the corresponding dts node is supposed to be compatible
"syscon-reboot-mode" device and necessarily have an offset property
to determine which register from the regmap is supposed to keep the
mode on reboot.
