-RDA Micro UART

-Required properties:
-- compatible :  "rda,8810pl-uart" for RDA8810PL SoCs.
-- reg        :  Offset and length of the register set for the device.
-- interrupts :  Should contain UART interrupt.
-- clocks     :  Phandle to the input clock.

-Example:
-
-               uart2: serial@20a90000 {
-                       compatible = "rda,8810pl-uart";
-                       reg = <0x20a90000 0x1000>;
-                       interrupts = <11 IRQ_TYPE_LEVEL_HIGH>;
-                       clocks = <&uart_clk>;
-               };
