GS101 supports a couple different reset types via certain registers in
the SYSCON register map.

Add a binding for this.

+description:
+  GS101 supports a couple different reset types via certain registers in the
+  SYSCON register map. This map is retrieved from the parental dt-node. So the
+  gs101-reboot node should be represented as a sub-node of such a node.
