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



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>;

	};
