dt-bindings: timer: sprd-timer: convert to YAML

Browse source 
Convert the Spreadtrum SC9860 timer bindings to DT schema.

Changes during conversion:
  - rename file to match compatible
  - add sprd,sc9860-suspend-timer which was previously undocumented
  - minor grammar fix in description

Spreadtrum timers
The Spreadtrum SC9860 platform provides 3 general-purpose timers.
These timers can support 32bit or 64bit counter, as well as supporting
period mode or one-shot mode, and they are can be wakeup source
during deep sleep.
Required properties:
- compatible: should be "sprd,sc9860-timer" for SC9860 platform.
- reg: The register address of the timer device.
- interrupts: Should contain the interrupt for the timer device.
- clocks: The phandle to the source clock (usually a 32.768 KHz fixed clock).
Example:
timer@40050000 {
compatible = "sprd,sc9860-timer";
reg = <0 0x40050000 0 0x20>;
interrupts = <GIC_SPI 26 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&ext_32k>;
};
