dt-bindings: timer: actions,owl-timer: convert to YAML

Convert the Actions Semi Owl timer bindings to DT schema.

Changes during conversion:
 - Add a description
 - Add "clocks" as a required property, since the driver searches for it
 - Correct the given example according to owl-s500.dtsi

Actions Semi Owl Timer
Required properties:
- compatible : "actions,s500-timer" for S500
"actions,s700-timer" for S700
"actions,s900-timer" for S900
- reg : Offset and length of the register set for the device.
- interrupts : Should contain the interrupts.
- interrupt-names : Valid names are: "2hz0", "2hz1",
"timer0", "timer1", "timer2", "timer3"
See ../resource-names.txt
Example:
timer@b0168000 {
compatible = "actions,s500-timer";
reg = <0xb0168000 0x100>;
interrupts = <GIC_SPI 10 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 11 IRQ_TYPE_LEVEL_HIGH>;
interrupt-names = "timer0", "timer1";
};
