dt-bindings: interrupt-controller: Convert marvell,cp110-icu to DT schema

Convert the Marvell ICU interrupt controller to DT schema format.

Add the missing addressing properties to read and translate child node
addresses.

Drop the legacy binding description and example.

+title: Marvell ICU Interrupt Controller
+
+description:
+  The Marvell ICU (Interrupt Consolidation Unit) controller is responsible for
+  collecting all wired-interrupt sources in the CP and communicating them to the
+  GIC in the AP. The unit translates interrupt requests on input wires to MSG
+  memory mapped transactions to the GIC. These messages access different GIC
+  memory areas depending on their type (NSR, SR, SEI, REI, etc).
