dt-bindings: serial: add a new compatible string for SC9860 

SC9860 use the same serial device which SC9836 uses, so added a new
compatible string to support SC9860 as well, also added an example
of how to describe this serial device in DT.

* Spreadtrum serial UART
Required properties:
- compatible: must be "sprd,sc9836-uart"
- compatible: must be one of:
* "sprd,sc9836-uart"
* "sprd,sc9860-uart", "sprd,sc9836-uart"
- reg: offset and length of the register set for the device
- interrupts: exactly one interrupt specifier
- clocks: phandles to input clocks.
Example:
uart0: serial@0 {
compatible = "sprd,sc9860-uart",
"sprd,sc9836-uart";
reg = <0x0 0x100>;
interrupts = <GIC_SPI 2 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&ext_26m>;
};
