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 at 000000 {

serial at 0

Addressed this.

With that,

Thanks for your review,
