Subject: [PATCH] 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@...50000 {
-		compatible = "sprd,sc9860-timer";
-		reg = <0 0x40050000 0 0x20>;
-		interrupts = <GIC_SPI 26 IRQ_TYPE_LEVEL_HIGH>;
-		clocks = <&ext_32k>;
-	};
