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.
