serial: 8250_ingenic: Add support for the JZ4770 SoC

The JZ4770 SoC's UART is no different from the other JZ SoCs, so this
commit simply adds the ingenic,jz4770-uart compatible string.

 * Ingenic SoC UART
 
 Required properties:
-- compatible : "ingenic,jz4740-uart", "ingenic,jz4760-uart",
-       "ingenic,jz4775-uart" or "ingenic,jz4780-uart"
+- compatible : One of:
+  - "ingenic,jz4740-uart",
+  - "ingenic,jz4760-uart",
+  - "ingenic,jz4770-uart",
+  - "ingenic,jz4775-uart",
+  - "ingenic,jz4780-uart".
 - reg : offset and length of the register set for the device.
 - interrupts : should contain uart interrupt.
 - clocks : phandles to the module & baud clocks.
