Convert the Actions Semi Owl timer bindings to DT schema.

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

I do not see any rename happening, anyway, this is not a change to the
binding, skip mentioning in changelog.

Clocks were not in original binding, so you add clocks in the first
place.

timer1 is a required property. Above is fine but you need allOf:if:then:
block customizing/constraining it per variant.
